Mixing Motul Oil and other synthetics

**SuperAvant** · 06-16-2008 09:16 AM

I have a question here as I am not too familiar with Motul oil products. I purchased 10 quarts of this stuff from a race shop a good distance from my home. I didnt even think to buy a few extra quarts to top off between oil changes. From what I remember this is ester based correct? Can you mix this stuff with Mobil 1 or any other synthetic between oil changes to top off the oil? TIA

No one huh?

Motul is an ester, yes.

I know its ok to mix dino-oil and regular synthetic, so in my non-professional opinion I would say your ok to mix something like Mobil 1 in there.

I don't think it's bad. But I think your engine will like some sort of consistency.

i use motul 8100 and didnt have any last week to top it off before a long-ish road trip. since the car will going in for service soon, i just topped it off with some Pentosyn 5w-40. seems to be fine
