The fluid tester was testing for CO2. I’ve also had a compression test done and it was perfect I am stunned. I’ve already ordered the test kit from black stone labs but I reckon it will take some time to get here

No, none. Touch on wood.

I have reached the point of selling my car although I adore it. The test was done routinely by a tuner who does these tests to cars he is going to tune

I wasn’t chasing any problems. The test was done by a tuner who routinely did these tests to cars he tunes.

Hi, A co2 leak test was recently done on my car. (2015 F20 LCI 120i n13 engine) There are absolutely no issues with the car, no codes, no misfires, nothing. A compression test was also done and it was perfect. The fluid in the tester turns slightly green, although in the tests manual it...

Would using TCW3 additive damage engines with nikasil bore liners? Does TCW3 oil contain sulphur?

Hi, I couldn't drive my car for 2 months as I was away. E20 gas has been sitting in my cars tank for 8 weeks. Should I be worried? Any chance of it being contaminated?

The way I understand it TCW3 mixes well with E5 gas and hydrocarbons like Toluene and Xylene but doesn't with ethanol. My main question is will it mix with E15 Gas? P.S: Ethanol I use is %98 pure.

Hi, I use 75 percent E5 gasoline (95Ron/roz) 15 percent toluene and 10 percent ethanol as fuel in my car. (And also 30ml of TCW3 per 18 liters of total fuel) - This is done for octane enhancement purposes. Today I've noticed that although TCW3 seems to happily dissolve in Toluene, it's not...

Originally Posted by RDY4WAR I found the email exchange I had with the tuner of that car. I asked him the same question of how the ethanol fuel could handle as much spark advance and pressure as the leaded gasoline with a much lower octane rating. This was his response. "As the piston moves up...

Is ethanol or xylene more corrosive?

Originally Posted by Loi Ethanol would be more resistant to knock. I run ethanol on both of my cars. How come ethanol is a better anti-knock agent compared to xylene and toulene while still having lower mon and ron ratings?

Although Toluene and xylene have higher higher mon and ron octane ratings I was told that ethanol burns cooler and thus is a better anti-knock agent. Toluene and xylene both have stoichiometric ratios close to gasoline, and ethanol does not. Which of these chemicals is the best anti-knock...
