Reviews of Mobil engine oil

i use 5w30 in mine and it runs great. really quiet.

i use 0w-40 on my vr6 with 80K miles. runs fine

Recently got my first oil change at 5K and used mobil 1 0w40. The engine is now louder as compared to what it originally was. Not sure if it is the oil being too thin? or perhaps the cold weather.

Put in 4.0 US Qts. of 0W-40 Mobil 1 (extra due to larger filter). Started the car briefly to check for leaks. Based on my measurement, with the new larger filter, 4.0 quarts will bring you to about 60% up the crosshatching on the dipstick. So, I added another 1/4 quart (8 oz) and that seemed to bring it right to the top. So, 4.25 quarts is what I will be going with in the future.

To bad Walmart stopped stocking Mobil Delvac1. $32 + tax for 4L of full synthetic. Probably one of the best, if not the best oil for Pre PD TDI's...

I bought a case of Delvac1 5W40(4x4L) Synthetic at a distributor not too long ago for $128 tax included. On a side note, it was cheaper to buy the Delvac1 than the Mobil 0W40!

As for oil, I suggest using Mobil 1 0w40. They recently started carrying this in town and my mpg has improved with it.

I switched to Mobil1 5w-30 shortly after purchasing my 99.5 1.8T and I haven't had any problems, as a matter of fact my cold-weather starts noticeably improved and oil temperatures seem to be consistently lower during normal operating conditions.

changed my oil two weeks ago to mobil 1 5w30 and she runs very smooth

I've used 15w50 Mobil 1 with no problems. It wasn't bad. It acctually good. But, it didn't make one bit difference, so I've used it only once, and went back to the regular 0w40 Mobil 1.
