Premix amount

[jdmr_neil]

Ok, so i still use my omp which after seeing my internals, it's working well. Still I've decided to premix but how much should i add? I've bought some 250ml squeezy bottles and some decent 2t oil so is 125ml a full tank the way to go?

Premix

So I know there's a lot of info on other sites, but mainly on US sites with measurements I don't understand and thought it would be useful info on here. My car is virtually stock still using omp and my plan this year is to premix for abit more piece of mind, specifically on track days etc...

I use 250:1 with OMP
100:1 without

In US speak, Protek-R recommend 4fl oz. (118ml) for every 12 gallons (54 litres) in normal use. They supply these 4oz. squirt bottles that I keep and refill so I never have to measure it out again. They suggest a ratio of 100/80:1 for more track focused use.

100:1

25 litres of petrol stick 250ml of premix in
50 litres it's 500ml etc

I have 150ml bottles and I use that with every fill up. If you use 200, 250, 300ml it won't matter much. All your choice. It won't harm the car.

I use 125ml per tank of fuel. I've also seen its suggested too fill up and premix 4 times in a row then on the 5th don't premix so there isn't a excessive build up of it from obviously not completely emptying the tank before every refill. Not sure if it really matters but that's what I've been doing. Seems to be mostly up to the individual rather than a strict way of premixing.
