Hey guys,
I've been running my GTT on Caltex 98, and just yesterday switched to BP Ultimate (there was about 1/3rd fuel left in the tank).
It was running fine before that, now today when I started it up it felt a bit funny, drove it up a few streets, pushed my foot a little further and it felt like I had no power. Turbo spools etc. So I went onto the highway, planted my foot in 4th, felt like there was no boost (boost gauge wasn't moving either, but the turbo was spooling). I was like uh oh, so I drove to an empty street, dropped it into second and floored it, I heard a few pops, of what I would say sounded like misfires coming from the engine, with still no power (this was at 4k~ or so rpm, so when the boost would kick in). Almost stalled at the lights taking off..
I drove around steadily for another 10 minutes or so and then all of a sudden everything was fine, drove around for another 30 minutes and I swear it was even smoother than before.
My question is.. Is this because I mixed the two fuels? Or something more sinister? I have heard rumors that the Caltex 98 isn't actually 98.. So could this f**k with timings or something?
Cheers
