Owner reviews for engine oil

Vw recommends Castrol I wouldn't use anything else

They should be using 0W20 full synthetic oil (not synblend crap). Its not going to hurt running the 5W20 in it instead but next time mention it at write up. Mazda claims benefits such as better cold start protection and better efficiency among other things.

When I changed to full ester Motul in my motorbike, there was a noticeable reduction in the time it took for the startup rattles to quieten down.

They were using the wrong oil- Shell 0-30, and it was clicking pretty loud when cold. I got the oil change kit from Duetche Auto and put in the Luqimoly. What a difference. I cant recommend it more. You will love it.

I also got the 3 year old oil changed and the radiator flushed.

Right now I run 15w-40 Shell Rotella Diesel engine oil in my bug. You can see below the Zinc & Phosphorus PPM (the higher the better). So you can see that Shell Rottela & Napa Diesel oil has fantastic for wear protection for the aircooled flat tappet cams.

I use 0W-20 Pennzoil Platinum for our 2013 Accord Sport.

Castrol Syntec 5w40 is stout enough for the 10,000 mile oil change.

Amsoil 10w40 and there 20w50 non race oil it says right on the bottle it has a heave zinc compound for extreme use. I use the 10w40 in my Rocco 16v my wifes mk1 gti , and a lot of other vehicles. No upper end noises on any of them. Worth it weight in gold!

So did the oil change today. Mobil 1 0w-40, changed the filter as well, after about 20 miles I can sense a bit more smoothness and slightly better throttle response as compared to whatever else was there.
