Owner reviews for engine oil

Motul xclean, amsoil signature series, valvoline max life, and penzoil ultra platinum are the favorites.

Super happy with the guys at PIA, and they use Eneos 5w40.

Ive only bought at walmart. $21.97. My turbo calls for an ingredient thats in the pennz synthetic

I also found out the filter (Mobil 1 extended performance) was about $6 cheaper there too

Walmart. Shell Rotella 5qt for $20. Or Mobil1 for less than $25 if they're out of the Shell and K&N filters always in stock.

My flavor of choice has been Motul 8100 x-cess (5w-40) every 5K or 6 months.

Been using Mobil1 5W-30 since 1998... GTI now has 232,500 miles and is smooth as silk. I do oil changes on the dot at 5K miles.

I always use VR1 (Valvoline) 20w50. Excellent oil. The car runs beautifully on it and has had no issues.

I happen to use Castrol in all my gasoline powered vehicles and have had no oil related issues. Given that VW promoted Castrol and, more importantly, that I prefer Castrol in general, I’m staying with Castrol when I can... I've had no oil loss in the Tig with Castrol and see no reason to switch to a different brand just because some MBAhole behind a desk made a profit driven decision to switch suppliers.

I use 15w40 GTX Diesel Castrol oil, it works.

The part number they listed for each quart of oil was G-E55-540-1B-DSP . Look that up and you'll see why oil changes are expensive. Somehow I don't think the oil is better than the Mobil1 I buy at Walmart at $24 for 5 quarts.....
