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 Ford 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 negative 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.
Do I recommend this oil? You betcha! I wouldn't use any other oil in a million years.
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 starts its refining from very very high quality oil – you pay for what you get.
That’s right Mobil 1 starts its life as a PAO oil – the highest rating you can get. So it’s already the best before it starts (one reason why it’s so expensive).
Some other Synthetic oils live on the “edge” and actually start life as a grade 3 or tier 3 oil then its Hydrocracked to try to make it better. Don’t get me wrong these are still very good oils but in reality Hydrocracked oil should not be as expensive as Mobil 1 by a long shot!!!!!
Another reason you might want to consider Mobil 1 over the others is that Mobil is an oil company and therefore has access to high quality oil reserves first – other smaller engine oil sellers have to purchase oil off the exchange and have to dose their oils up with additives to make them better. Feel free to have a look and you will find most small engine oil sellers started life as oil additive businesses.
Another thing I like about the Mobil 1 product is as an engine builder I can choose any viscosity I require. The others usually cannot as they have dosed their product up with so many different additives that some of their product cannot be used in some engines.
So to sum up – Mobil 1 is the best engine oil just not from the protection it provides but the fact it actually starts life as the best (PAO) oil available.
It starts life as the best oil you can by before it is refined up to Mobil 1
Because other companies are Hydrocracking grd 3 oils and charging the same price as Mobil 1 this may force Mobil to do the same and downgrade their product over time!
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, 0-40w. 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 Sport 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!!
