Engine oil Mobil or Shell

Same here 0W-40 since new, now have over 140K, runs like a dream.

Mine's had Mobile 1 since day 1. Up until 45K-ish it was 5w- or 10w-40(?) Anyway, I switched to 0w-40 and I know my milage is a tad better and I swear the seat of my pants tells me the engine has more... spunk.

0w-40 is a great oil for the VR6. It's not too thin. At operating temp, it's a 40-weight oil and viscosity-wise is no different than 5w-40 or 10w-40. It is thinner than these oils at start-up, which isn't a bad thing. I used 0w-40 for many miles without any issues and the engine is still in amazing shape at 211k+ miles. FYI, 0w-40 is used as factory fill in all Mercedes AMG engines. If it's not too thin for those beasts, then it's not too thin for a VR.

0-40W here all year round in Chicago 138k miles and still going strong

I just changed my oil and filter on my 2006 GLI 2.0T. I used Mobil 1 15w-50 and a MANN filter purchased from the VW Dealer. My best friend is an awesome Audi/VW tech and he advised me that was fine combo.

Josh, just get yourself a gallon of Rotella syn 5W40 oil from Wallysmart. It's a perfect solution for an old buggy like yours. I think it's around $14/gallon and is ideal for year round use. you may even pickup a couple of MPG.

On the 16v I had I also had a cyl head temp gauge and temps dropped from 240F to about 210F when I switched from Mobil 1 to AMS, so did my oil temp drop fromt eh 250 to 215 range.

when i had my 2000 Jetta TDI I used Shell Rottela T full synthetic. 5-40 i think. blue bottle you can get at your local mega-lo mart good stuff and cheap check there web site.

i use mobil delvac 1 5w40 synthetic oil in my 2000 beetle tdi.

did my first oil change 2 weeks ago, put Mobil1 0w-40 in... and I'm getting better gas mileage than I was on the factory oil
