Mobil 1

[RJM3]

Hello for those using Mobil 1 I was just curious as to the viscosity ? Do you use 0-40 or 15-50 ? Are there any great differences? I notice on the container of 0-40w it mentions European formula or something to that effect....Any comments would be greatly appreciated...regards jer

I use Mobil 1 15W50 during the summer track season, and then switch to Mobil 1 10W30 during the winter (no track events).

I use 0W-40 Mobil 1 in my 84 Carrera. Street use only.

The "european formula" is probably just a trick to make it seem more interesting. I've noticed that american companies often use phrases such as "euro spec" etc. to make their products seem more exotic.

15W50, street or track.

15-50 street. Usually wait until WAL-MART has those 5 quart jugs in stock for around $18...then I stockpile like crazy!

I also use the 15 50.

15W-50 in the 911.

I have not found a source for 0W-40, which my Mercedes needs.

15 - 50 here also. But I'll add. I don't go over 3000 rpm's until the needle starts to come to life on the temp gauge.
