Interesting thread about 2 stroke oil in Petrol Vehicles

[cmar]

A similar idea to the one over in the diesel section. http://www.ls1.com/forums/f48/been-testing-oil-91206/

I've been trying this in my two vehicles, as they both run on E10 most of the time. I've always used Moreys or Flashlube or similar for this reason, maybe it works, and maybe it doesn't, but I've never had to replace a fuel pump or injector, and I use plain standard Bosch plugs not platinum ones, and they still do 100,000 Km easily and come out clean. One car is now approaching 300,000 Km and still runs like new. Both cars seem to run fine on Valvoline Super outboard at 30ml / 20 litres, which is incidentally the same rate that Moreys and Flashlube recommend for their products. The best thing is that is is way cheaper.

It's the first I've heard of someone running it in unleaded, I ran it in my old deisel troll with satisfying results

wouldnt reccomend in in efi vehicles, 2 stroke oil doesnt burn completely(have a look at the exhaust of a 2t engine, nice nasty black gummy residue) which will coat the o2 sensor in the exhaust destroying it and causing excessive fuel use

Normal two strokes run 25:1. This is more like 600:1. Don't forget also that this is TC3 outboard oil, it is designed to burn cleanly and completely. And as I said the ratio is similar to the ratio recommended by Moreys, and Flashlube, which are certified safe for sensors and cat convertors. I've been running them in one car for almost it's whole life, the first o2 sensor lasted 180,000 Km the replacement one is still in there at 260,000
Also the guys in the thread (aircraft engineers) have been running it collectively for 100,0000 miles withought issue in EFI vehicles.
