HI

I have a rx7 13bt s5 with OMP, but to help on lubrification of chambers, I buy Idemitsu Racing Rotary Fuel Lube (Premix) - Synthetic Blend (1/2oz per gallon of fuel). Any one know if this quantity (1/2oz per gallon) is for a car with OMP or without OMP?
I'm using this quantity of oil to premix in my car (that have OMP), and the car run very well, but I don't know if this is correct?!

Regards

 

For cars with out an OMP they usually pre-mix at 1 oz to 1 Gal. Mixing at 1/2 oz per Gal dose seem like over kill though. I use Pettit Racing's Protek-R it comes as a 20 pack of 4oz bottles and you just put one in every time you fill up, makes it easy to remember and actually do lol.

 

one ounce per gallon of gasoline.
the bottles of two stroke oil are usually 16 ounces.and the Fc Gas tank is 16 Gallons,depending on model.One bottle per full tank is a normal measure.
If your Omp is Working Fine,then there is no real reason other than "assurance" that your Internals will be lubricated..If it is working then it is just extra money spent.
The S5 Omp is Electrical too.So If you decide to Premix,the OMP cannot be taken OFF the car,and disconnected from the Wiring as it will send the Car's ECU into LIMP mode.(and run Like POOP!).

 

1/2oz per gallon of Idemitsu is plenty for non OMP cars. A buddy of mine has run that ratio on his BP for over two years.

 

I run 1 oz per gallon with no OMP but I wonder if that's not overkill sometimes... when I did have the OMP the car sure hadn't blown through a quart of oil every time I filled up on gas...

 

my s5 the pump is disconnected so i have been running 8oz premix to 10 gallons of gas for over a year without any problems. i use whatever premix is on sale and i have put over 13000 miles of hard driving so far

 

1 oz to one gallon makes a lil bit too much smoke.

i run .5 ox per gallon and she runs fine.

 

only thing about the omp is it can pick up dirty oil
