Castrol Magnatec STOP-START 5W-30

Excellent oil – I've never left a review for motor oil before, but I had to after using this stuff. I drive a 5th gen Honda prelude and I've always given it regular oil changes with fully syn premium brands. But it's always consumed oil at a high rate, and lately it got so bad I thought the piston rings were finally gone. I was recommended Castrol Magnatec by a… Read more

mechanic so tried it out and I just can't believe how different it feels. I took the car on a road trip recently and covered 1200 miles over a week, and I was shocked to see that the level hadn't even budged (on my car 1200 miles would be at least half a quart normally). Although we did also clean the pcv valve which I'm sure helped. But on top of that it feels so smooth and the engine feels more responsive again. It's also the cheapest oil I've ever used in my car as well. I highly recommend it.

Best oil I have ever used – I have Chrysler Sebring Convertible with a V6 2.7 engine that tended to sludge up when I had it in Florida. I shipped the car to Europe 12 years ago and changed the oil to Magnatec 5W30. , 95000 miles later I have had a smoother engine, more MPG and No Sludge. Great oil for a engine that has been written down as unreliable. Show details

Perfecto – I tried a number of different oils from mineral(15w40 nulon etc)semi synthetic (10w40 megnatec etc) synthetic (Penrith 5w40 -Castrol edge 5w30 etc) till I came across megnatec 5w30 stop start great oil with a difference really happy finally oh and on a last note I also found nulon 5w30 an excellent oil  Show details

Great oil – Before changing the oil to Castrol magnitec my car had noticeable tappet noise. Immediately after the oil change and filter replacement the engine was notably quieter. The engine definitely feels a lot smoother than before. Definitely recommend this oil to anyone who wants to preserve their engine and reduce wear.  Show details

Good oil – After changing engine oil from nulon long life to Castrol magnates, actually nothing changed much. What I can notice is it is more easier to rev up a little bit when accelerating. Other things like fuel economy, noise level, power does not changed much. I’ll say this is a good oil, concerned with its price, and it’s a "full" synthetic oil. Sometimes even cheaper than OZ brand Nulon and Penrite.  Show details

Excellent oil – Been using Magnatec oil for many years, and wouldn't use anything else. It does exactly what it says it does, and the engine in my car loves it. Oil pressure is strong on start-up, and keeps strong even when hot. The previous oils with similar viscosity I used caused my engine's lifters to tick when hot, but not with this oil. The engine spins freely, and effortlessly. HIGHLY recommended oil!  Show details

Great Oil from Castrol. I won't change brands, only oils – I used many brands of oil over the years without really finding anything good about them. I've been using Magnatec for over 20 years with good results on Mitsubishi cars and now a 2010 suzuki swift.& a 2015 SUZUKI Swift.. The only problem I did have, was a rattle in the engine when it was cold and the oil had all drained back into the sump. I… Read more ·  2
