Mobil 1 Oil Designations???

[nfpgasmask]

Good question. I've been using Mobile-1 10W-30 for the last few oil changes and I am due for one in 200 miles. I plan to keep going with Mobile-1....

So I got some Mobil1 10w-30 (SuperSyn Technology Fully Synthetic) and plan to change the oil this weekend. I looked in my user manual and it says USE ONLY API, SE, SF, SG, SH, or ILSAC GF-1 Quality Oil
Additional designations of quality may also be present, but SE, SF, SG, SH or GF-1 must be included.

So I look at my new bottles of Oil and they don't seem to match any of those??? The bottle has ILSAC GF-4 API SM, SL/CF

Am I good to go, or did I find the wrong stuff?

Enquiring minds want to know!

I wasn't questioning the use of synthetics (Good article by the way), rather if I have the right one for my VX.

I do see that Mobile1 meets the API (Not actually sure what all these letters mean, but I shure can repeat them ), but the Owners manual says it also needs one of those other letter combinations. I guess that's where I'm trying to be carefull.

Sounds like GASMASK is saying that Mobil1 is Mobil1... I must have the right one if that's the case and I see that others are using it.

Anyone disagree? Would I be better off with something that has the right letters on the bottle, or does the Mobil1 Synthetic definitly Meet/Exceed these requirements?

Here is a link that will tell you all about the ratings. Mainly it is government thing. The oils must meet certain standards and every time they update the standards they change the #'s or letters.
