Owner reviews for engine oil

Me running 5w50 Amsoil SSO full synthetic or 0w50 Eneos or 0w40 Amsoil SSO if being used in winter (down to -40F, and yes, I've driven these cars down to that cold)

Synthetic is better, always. Higher not viscosity has better shear protection. A good additive package that has great shear protection lets the housings wear slower.

Yes you can I’ve been using 10w40 castrol ever since I got it and I’ve been fine

I used Mobil1 for a decade and around 50k with no issues.

Quaker State oil is recommended in the Hyundai manual but you can absolutely use other brand too , i have used Mobil 1 / Vavoline / Castrol and Pezoil the end i picked Valvoline high mileage Synthetic oil the best of all all other brand the oil burn brown quickly

I’m at 80k miles and only used mobil 1 ESP x2 0w-20, don’t wanna mess around with any other viscosity, I’m not smarter than VW engineers ????‍♂️

I run LM 5w-40 as recommended by my tuner.

The oil type is likely fine, but the viscosity isn't. Ignore what the book says, get the 5W30 out of there. The PDs love to eat cams, and running 5W30 makes the problem worse. Me personally, I run Shell Rotella T6 5W40.

I've run Redline in my '01 Golf & my '10 Touareg TDI's for Hundreds of thousands of miles. No worries!

I paid $90 bucks for a full oil change the first time, using motorex. now for my 2nd change, she's getting Rotella T6 because it's cheaper. I put on too many miles a month to shell out $90 bucks every 3k miles.

I have been running Mobil 1 0w-40 since new with over 50k miles on different Big turbo(80k total miles) setups and always replacing seals and gaskets due to oil leaks(its some really thin oil).
