Reviews of Mobil engine oil

I too use Mobile1 0w40. Burns maybe 1/3 of a quart every 7000 miles. Not bad at all.

When I did my oil change about 800-900 miles ago I used Mobil 1 0w-40 and so far I'm loving it more than which was last in there which was 5w-40 used at a VW dealer them selves.

I have apr stg2 and i change my oil every 5k with mobil1 5w30 and it never burns a drop!

mobil 1 5-40 diesel truck blend has it, just referenced my blackstone labs report after 6k miles was still over 1000

I have ran mobil 1 0w-40 for a long time without issue but am thinking of switching to thicker this change as it's starting to leak out one of the oil seals into compressor housing.

I know when I put my stroker block in with stock head/turbo I filled it with 0w-40 and I would get low oil pressure when deaccelerating down hills.. Low enough the light would flash on, got my freaked out! with the new head. and my 71r 72a/r set up going on I'm swapping to 10w-40 mobil 1, because when I took the old head off there was a TON of carbon build up for the small amount of miles I had driven the new block around(less then 2,000 miles). I had changed the old twice already(once ot get the break in oil out and once again at 500 where I dropped the pan to check for metal and such and up in a new pick up tube for piece of mind). I have good reason to believe the 0w-40 is just too thin for the clearances for stroker pistons and such. I'll report back once the car is up and running with the 10w-40 in it. If the oil pressure problems persist I'm thinking about stepping up to 10w-50, but Im in southern California so YMMV depending on how cold/hot it gets around you.

Over 50k big turbo miles on Mobil 1 10w 30 full synthetic. I love the oil, try some 10w 30 :thumbup:

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).

I'm not really too sure about the weights, but I highly recommend using specially formulated euro blend oil. I believe that is 0W-40. I personally only use mobil 1 euro blend. It is expensive but your engine is not the place to get cheap.

I switched it to Mobile 1 high mileage, and no more smoke, and it now, I kid you not, burns less than 1qt/3-4k miles!
