Delvac 1 + Mobil 1

[buster]

Are Mobil 1 and Delvac 1 compatible? I'd like to mix these two. I have a 5qt jug from walmart I bought for $18 and I have 2gallons of D1 I have yet to use. I'd like to add the Delvac 1 to M1 for some extra cleaning power.

Should be no problem mixing the two. Now, whether you'll get any magical results is questionable.

Without getting into the basketball, golf ball thing, would there be a problem with D1 having a different base oil? Does it have a different base oil?

PAO's are one part of each oil's base. Delvac 1 uses TMP and PE polyol esters. M1 SS uses TME esters. Delvac 1 has a higher percentage of AW additives such as Boron, and ZDDP. Delvac also has a better Detergent-Dispersant package for HD use. M1 has higher FM additives, but a good set of AW adds (Moly, ZDDP, Boron) but at a lower level. Actually, I would think they would complement each other. I see no problems with mixing the two. PS. If the M1 SS is 10W30 and the Delvac 1 is 5W40, expect a slightly different viscosity, such as an 8W35. [ June 05, 2003, 11:07 PM: Message edited by: MolaKule ]

Thanks Mol, that is what I was looking for.
