I just got done resealing a new oil pan and replacing the motor mounts and I am going with Mobil 1 full synthetic 15-50. my question is I have some m. mystery oil and am wondering if it is something I can add to the mobil 1. It says good for oil and gas. I am wondering if anyone knows about this. I did search add read about people adding it to dyno juice and having good results, just no synthetic talk. any input is appreciated.

 

i started using it a few months ago... about 3 ounces per tank... engine feels noticably smoother

 

I dont MMO is something you add to your oil, its something you mix in gasoline.

 

put it in your gas....itll clean your fuel system out and its a bit like premixing except that its not....

 

It is not a good idea to use additional OIL additives, especially in synthetic oil. Their additive packages are formulated to match their chemistry, and anything additional is likely to do more harm than good.

The use of MMO in fuel is a separate subject.

 

FWIW, I've been using Mobile 1 15-50 about a year now with about 4 oz. of MMO (I guesstimate) to a full tank. No issues on a relatively stock car. I agree with others, don't put it in your oil.

 

It says crankcase oil. my bad. I know it goes in with gas. good info concerning not adding anything to synthetic oil. just trying to find out since I am switching to mobil 1 for the first time.

 

I've used it both as premix and in the oil with great results for the past several years.

 

I put in 4 ounces of MMO every fourth or fifth tank.

 

SGTblue and Jonski,

Do both of you premix? Or do you just run it in the tank anyway?

No.
Well, I guess if I'm adding MMO to the gas you could consider that pre-mixing. But I'm still running the OMP as normal.

 

My OMP is intact, I just put it in every once in awhile to keep things clean and lubed.

 

Thanx guys, i think i will try this on my next fil up
