Owner reviews for engine oil

I've been using amsoil for the past 2 oil changes. No complaints, car seems to idle a little better and cold start sooner.

I'm not really too sure about the weights, but I highly recommend using specially formulated euro blend oil. I believe that is 0W-40. I personally only use mobil 1 euro blend. It is expensive but your engine is not the place to get cheap.

Loving the oil, just got my analysis back and it looked great!

this oil is fantastic. the car runs PERFECT. it is a bit pricy but i dont really care. i've used it for +60k doing oil changes every 5k miles... as the report shows, the engine is WAY better than perfect.

I have been using liqui moly 5w-40 in my 2009 2.5l for the past 30k miles and i think its the best oil. recently i have discovered their MoS2 anti friction additive and put that in my last oil change. the car runs very smoothly and should last a long time with its strong wear protection. also the car consistently achieves good MPG.

I switched it to Mobile 1 high mileage, and no more smoke, and it now, I kid you not, burns less than 1qt/3-4k miles!

The engine with the new oil runs so smoothly, I can literally stand a coin on top of the intake manifold and the coin won’t fall.

I have a 2010 VW Jetta 2.5 with 48,000 miles todate. The dealer used Castrol and on the last change Valvoline. Now I'm doing my own oil changes etc. Currently using Mobil 0w-40. Since I've had the car the oil level drops so little on 10,000 changes that I can't measure it. The last oil change included 4,700 miles of hot Interstate driving. After it was changed I had the oil tested and basicly it had a lot of life left. Looks like the 2.5 is very easy on oils.

I have used royal purple once and didnt really are for it... But now i have been using motul 8100 x-cess 5w40 on my 06 2.5l rabbit for the past 5 oil changes and it works amazing... I'm going on 6500 miles right now and it still has a yellowish tint to it, like clean oil! I do some autocross, some quarter miles, and I drive a little aggressive... This oil is awesome an I would definitely recommend it...

I also started using it in my bike after switching from Mobile 1, and it's the best thing I've experienced so far with the wet clutch, keeping the shifting very smooth.
