Engine oil Mobil or VALVOLINE

same here in IL - 132K still going strong

I use Mobil 1 0w40 year round in Missouri, never had a problem.

I have seen NO reason not to use Mobil 1 5w40 in a NON PD TDI motor. I know many that use it and no problems RELATED to oil. They do not coke up and the wear isn't there. I have used 5w30, not even 5w40 Mobil 1 in my VW/Audi 2.4L engine in my Volvos for years and have seen the best results

I have used both 0w40 and 5w40 Mobil 1 in a 02 Jetta for a long time with great results.

I have used Mobil 1 for years in Volvo diesel cars, and they are known for cylinder wall wear, of course its a VW Audi engine. With using Mobil 1 5w30 over several hundred thousand miles, I have seen zero wear and have not needed to adjust the valves once, in several engines. I am convinced it works well.

I used mobil 1 5w30 when I did the 10K oil change as well.

i use valvoline 5w 30 and it hasent done me wrong...yet

I also have a 2.0 and run the valvoline synthetic. I started after 2500m and am currently at 29k. No scientific results here other than keeping track of mileage in a little notebook and looking back at the first month compared to the most recent - I'm averaging about 7mpg more.

All these problems are not present in the Valvoline SuperSynth 5W-40 sample. Furthermore, the results from this Valvoline are well below the Universal averages for this engine. This suggests that I should be able to run this oil for at least another 1000-2000 miles and still get an excellent report out of it! With it, my engine runs bit smoother and quieter especially at idle. At high engine speeds the engine feels more responsive and more lively. Another difference is that with Valvoline, I am observing improved efficiency. My 2.0 broke its own record of fuel efficiency: 34.3 miles to the gallon on high way. The improvement is 3.3-3.9 miles per gallon compared to Mobil1.

my v6 consumed almost a quart during the first 3,000 miles then it stopped (zero oil consumption!).
