Anybody ever use nitro methane oil as an additive????
Old Kimmer,
ALL oils are blends period, which is why there are fractionating towers to refine the crude.
But dont take my word for any of this. I Emailed my father in law, who for many years was in charge of Exxons oil research program. He has a PHD and did nothing but develop oil additives.
First the question then the answer:
Dad,
the question has been asked if you mix 50% 70 weight oil with 50% 30 weight oil do you get 50 weight oil or does the engine only see the 30 weight oil first then the 70.
There are some who want to use 70 weight Nitromethane racing oil as an additive because of the extra additives they put in that particular oil.

you may be as technical in your answer as you like these guys are all motor heads.
Dr. Turner:
The weight of the oil is based on viscosity. Therefore, if you mix a 70 grade with a 30 grade you will definitely lower the viscosity grade. The exact weight would have to be determined. However, I would like to point out that the additives in a racing oil are normally designed to combat high temperature oil oxidation and wear. Sludge is normally not a problem since the engine is usually changed out before any sludge would form. This is not the case in city type driving where sludge and varnish are the primary concern along with a good anti-wear additive. I know from experience that the best service station motor oil will normally out perform an oil that is strictly designed for racing when used in over-the-highway type driving. If you desire an oil that will give good performance in both racing and passenger car service, you should purchase a good 100 % synthetic oil such as Mobil 1 which has excellent oil oxidation stability and wear characteristics plus it will also give excellent passenger car performance
