When you are on a good thing stick to it - er sorry wrong brand :-)
I have been using Mobil oil for 33 years, originally due to price when I could buy a 1lt tin of 20W50? in Franklins (that was a supermarket like Woolies) when I got my first car. For the next 23 years I was able to buy the same or next era version at supermarkets etc at a good price. My last car, 1979 2lt sigma which I owned from new had the engine partially rebuilt (by me) at around 200k, Mitsubishi's back then and prior were notorious for rings wearing and burning oil (unlike Datsuns I had owned previously). I put a new set of rings in, pisto...ns were borderline which I later regretted for not replacing due to ring groove wear, and new bearing as they were cheap. When I queried the plastic wrapped new bearing size compared to what I had removed (and had on me) the service dept of the dealership said they had seen more wear on bearings that had done 20k compared to my 200k. I ended up selling that car at 350K many years later, still using Mobil oil, and to the first person who looked at it - and without driving it. Compression was down due to not replacing pistons which I realised after the rebuilt motor was run in but that was a borderline decision which in hindsight was wrong based on advise. When I got my next car, 1998 Toyota Camry V6 which I bought 2 years old with 44k on it I realised this engine was a was a precision built instrument I would never be able to rebuild to anywhere near the same tolerances. Appreciating this beautiful motor I decided to use the best Mobil oil to increase its longevity. (I don't replace cars frequently - and with current car now almost 20 years old that is the general frequency). I have used the fully synthetic oil since I bought the car in 2000, now has 265k on the clock and uses no oil at all. It has a very slight knock which was there when I bought it (was an undercover detectives car which may have been given a caning before run in properly), but that knock has not got worse in 220k.) I had been buying the oil at Supercheap when on special before they stopped selling it, then Repco when they had the big NRMA membership discounts every few months, but even then the price was expensive. I generally buy good value products, and Mobil 1 was no longer good value, but because I had been using it so long and my Camry was lasting so well I ignored the price. Currently 265k no oil burn at all. The oil does get a bit dirty by the time I change but when I replaced the rocker cover gaskets a few years back the rockers and cam were so clean!! Unfortunately my local Repco no longer stocks the oil so cant buy on 30% discount etc which makes it a very expensive oil compared to the opposition. There may be equally as good oils out there such as Penrite, Shell or Nulon, but when you are on good thing stick to it - if you can. I have used Nulon additive in a gearbox to quieten down 5th gear (79 Sigma) so have some appreciation for the brand but have no real experience in alternative oils to the Mobil 1 5W-30, Nulon, Shell, Penrite or whatever alternatives. Would be interested in peoples opinions now that Mobil 1 is no longer available at good discounts and other brands have better retail awareness/price.
This oil is excellent in the Buick 3800 V6, no complaints whatsoever...ok maybe oxidation is a little high. Shear stability is very good though and so is the additive package.
I have been putting it in this engine for a number of years now. I think the formula has changed once in the time I used but it still seems to be more or less just as good.
Purchased in March 2019.
"Simply the best"
I have now been using Mobil 1 for 20 years and never had any problems. I first used it in a XE Falcon with a rebuilt motor, after 330,000 km the motor was still ran like new and consumed little oil, the car was written off but the mechanic I sold the engine to pulled it down, found it still clean inside and with little wear. The next car is a 2003 Subaru Forester, started using Mobil 1 from the first oil change, it has now gone 480,000 km and still good, burns about 1 litre oil 1000 km, no engine noises or rattles. Third vehicle is a 2007 SY F...ord Territory with 320,000 km on the clock, engine still runs like new, and has never been opened, it uses about 1 litre of Mobil 1 between 15,000 km services. The exhaust system and catalytic converter is still the original, only one oxygen sensor has been replaced. The spark plugs only need changing every 150,000 km. I am using Mobil 1 on my FGX which has done only 40,000 km, barely run in, no noticeable oil consumption at all between changes. Another good reason for using Mobil 1 is that where I live the temperature can fall to as low as -8 in winter, Mobil 1 synthetic oils do not thicken like conventional oils which allows the engine to start faster, the oil starts circulating more quickly, and warms up more quickly. I would recommend it to anybody.
My go to oil! Outstanding engine protection.
I first chose to use Mobil 1 back in 2004 in my old Toyota Hilux 2.7L 4cyl ute, after hearing the story of my friend tell me how Mobil 1 increased the reliability of his sprint car during the racing season. As a privateer speedway racer, engine protection was paramount to prevent engine damage to his sprint car, as a good quality synthetic engine oil is much cheaper than a new 600HP sprint car engine!.
So after hearing his very interesting story, I thought I would give it a go. Firstly, before I go on, this oil is expensive, and is the only n...egative to this story, but I consider it an important investment, as you only get what you pay for, right? (A good tip, I buy Mobil 1 in a 20L drum from a Exxon Mobil wholesaler - more cost effective that way, and decant into 5L Mobil 1 containers when servicing our cars.) In my humble opinion, using a good quality synthetic engine oil in your vehicle/s is paramount to good car engine reliability. But I digress ... Back to the ute: After the first oil change with Mobil 1, (my ute already had 70,000 km on the clock at this stage), I was truly amazed how quieter the engine sounded, and how smooth it felt in all aspects of operation, from idling to gentle acceleration, under normal operation and during wide open throttle (WOT). During my ownership of the hilux ute, I had zero engine issues. I chose to keep using Mobil 1 in the ute for piece of mind, until it made way for the new arrival of child number 2. The wife and I currently own a 2009 Toyota RAV4 and a 2011 Toyota Corolla Hatchback, and we bought them both new. I chose from the very start to use Mobil 1 5W-30 in both of our Toyota's since their first oil changes, and continue to do so for piece of mind, despite the cost. Both our Toyota's engines run like new. The engines feel and perform exactly the same as the day we bought them brand new. They get serviced every 10,000 km, and apart from a couple of minor wear and tear items on the RAV4, (Alternator failure and leaking water pump), they have been very reliable vehicles. Only the RAV4 uses a little engine oil. At about 7,000 km after every service I have to top up the oil - around 100 - 300 mL of oil into the engine, well within spec of oil usage rates for the 2AZ-FE engine. Apparently the 2AZ-FE engines are known to use a bit of oil. Ours is not too bad. I can't fault Mobil 1 at all. It keeps our engines clean and does a good job of lubricating them as well. I'm even using it in the Honda lawnmower! I am surprised by so many consumers going for much cheaper oil, by either lack of knowledge or for sheer neglect for their automobiles. You can look down the oil filler caps of both of our Toyota's into the rocker cover and the cams look beautifully clean, a testament to the very high quality of Mobil 1 fully synthetic engine oil.
Excellent, stopped noisy camshaft tappets
Found this oil on heavy discount at Supercheap. Said they were not restocking Mobil because it was too expensive and didn't move. My dads Honda CR-V had a noisy top end. After flush, filter and new Mobil 1 the noise had gone. Not sure if I would pay the premium price next time around, but the CR-V sure does run well now.
This oil is very good for my engine, no dramas with it, this is the same exact oil that my local ford dealership uses in services, this oil is well recommended for anyone wanting some awesome performance, Mobil 1 is the best and even better than Castrol oils all the way
Only Oil I use
Lost my 4x4 in a river, pulled it out and drained cylinders via spark plug removal. Drove for 10km listening to a loud equal coming from the engine, pulled the dipstick and the oil had emulsified to a yellow custard but the engine did not seize and went on to do another 160,000 km fault free. Try doing that with a lesser oil.
Mobil1 5W30 Dexos1
Good quality synthetic oil. Car ran very smooth on it. Good cold start flow, much better than Castrol Edge 5W30 but I guess that because of it's PAO base stocks. Edge 5W30 isn't a proper synthetic.
Have had the chance to try Motul 300V 5W30. Sure it's twice the price but it's twice as good as M1. Improved oil pressure & VVTi performance.
smooth, proper synthetic(although it doesn't have as much PAO in it as older brews has)
RRP is a bit step
Mobil 1 starts it life as the highest quality oil you can get before it’s refined into Mobil 1
Being an Engine builder I get asked this question all the time!
Let me just start with if you use a reputable brand and the correct viscosity oil that has been internationally tested in a normal unmodified car – you will not have a problem. Also don’t believe the [censored word removed] about how one oil (Same Viscosity) can produce more power than another oil – the benefits are unmeasurable on a Dyno!
Do you want the best oil?
Ok – well all the engines I have built then tore down after racing for a rebuild I can honestly say Mobil 1...has been the best without a shadow of a doubt. The engines remain clean after furious driving conditions – which means the oil does not breakdown or contain impurities and also has the right level of detergents.
Mobil 1, 5-50W Full Synthetic Engine Oil
Bought 25 litres of this oil at Supercheapauto when it had the 20% sale. Very good oil for my Honda 2004 Accord Euro Luxury and my Nissan Maxima 3.5L V6. Both vehicle responded very well to this oil. Quiet start up, smooth engine response, stronger engine performance at higher speed, quieter tappets. Again, the oil cleans the crankcase very well. Engine crankcase very shiny in both vehicles. Lexus LFA uses this oil as factory fill, along with many other prestige and high performance vehicles made in Germany and Japan. Cheaper than Mobil 1, 0-40...w. Provides higher engine protection, at 50W!!! Especially under the hot, harsh Aussie sun. Smooth engine response. Higher engine temperature protection. Factory Fill for Lexus LFA and many other high performance German and Japanese vehicles. Tappets are quieter.
Awesome oil for the car. Cannot fault it in anyway except it is too expensive! At $95 for 5 Litres!
Tried it twice in my vehicle, has excellent cleaning properties. As well as making the car go a lot faster, smoother, quieter and more responsive than ever before. It cleaned out my engine crankcase really well, very shiny inside, and fuel economy improved as well. Zero oil consumption after 10,000kms per oil change. Too bad I won't be buying this oil anymore as it has gone beyond my budget. At $95 for a 5 Litre bottle at Supercheapauto, I will be switching to Castrol Edge Sport 0-40W at $85 for 5 Litre and then once I have tried Castrol Edge S...port for a year, I will try Shell Helix Ultra 5-40W at $65 for 5 Litre. Other than the steep price, it is an excellent oil if you have money to burn. You will definately notice a massive improvement in your vehicle engine performance once you switch from Mineral based oil to Mobil 1, 0-40W Full Synthetic Oil. If I have money to burn, I will keep buying Mobil 1, 0-40W oil for my vehicles. Cleans engine extremely well. Smooth engine running, quick response, fuel savings, quieter engine during startup, idle and under hard acceleration. The price...$95 for 5 Litre at Supercheapauto!!
Questions & Answers
Can I use mobil 10/30 to top up my 5/30 as required
my manual suggest 5w 30...but iam living in a hot tropical climate ..can i use 10 w 40 instead?
Hi there, my car is 2004 toyota crown, v6 3000 engine, it has engine oil leakage problem, can I use 5w50 mobil 1 as my engine oil to reduce leakage? thanks
Hi Leo, does your Crown have the 1MZ-FE 3.0L V6 engine in it? If so, the Mobil 1 DataTek website recommends Mobil 1 5W-30 or Mobil Super 2000 X2 10W-40.
Choosing the correct oil viscosity really depends on the climate you live in. There are lots of good websites out there explaining this. If your car is a Japanese import, then the manual will probably state a quite thin oil viscosity, similar to the northern states of USA, as it's quite cold in these regions.
In warmer climates eg. in the Southern hemisphere between the Equator and the Tropic of Capricorn, then you would want to select a slightly higher viscosity of oil, e.g. Mobil 1 5W-30 or 5W-50 if it's really warm.
If you have oil leaks in your engine though, then proper repairs and regular preventative maintenance of your engine really needs to be carried out on a regular basis. Regular engine oil changes with synthetic engine oil (preferably from new), = a happy healthy engine. Hope this helps.
