Engine oil Mobil or ELF

0w - 40 Mobile 1 was all I used for over 3 years, and the R was flawless until I sold her.

I use Mobil 1 0w-40 in my car (1.8T) because it is readily available, VW approved, has good performance and a decent price.

Mobile1 Full Syn 15w50 for my VR. I would like to think that if you changed your oil every 3000 miles under normal driving conditions than regular oil would be fine. Since I have some modifications and like to drive it like I stole it--sometimes-- than a better oil is good insurance.

ok i just did an oil change today. i put in Elf Excellium 10W50 Full Synthetic. anyways, the difference is awesome. much more free reving and "wanting to go faster" feeling. before oil change it felt tired and revs were lazy and engine had a 'fuzzy' sound when accelerating. anyways, all is good now

On that note, I currently have tried VW Oil from the dealer, Mobil 1, and Kendall Fully Synthetic and have determined that Mobil 1 5W-30 is the best mass-market oil out there to use. I run it 10,000 miles and the motor is as smooth as ever.

I use Elf, I switched over and won't go back.

Just started using it in my '03 3.0 (90K service). Elf 0W30. Notice a substantial increase in mileage! Hate the price, though...$13.95/litre CDN! And at 6.5 litres for the change...well, you get the picture.

That's just it.... I bet his iron levels were quite high on m1, just like everyone else is seeing.... which is why I switched to Elf.

I always get Mobil 1 0w40 ... it's 502.00 and VW approved !

I rebuilt a 1.6TD, my first rebuild about 16 years ago, and it had Mobil 1 15w50 since day one. I sold the car with 550,000 miles on the engine and it was still purring.
