Hello. First of all, I have read some of your posts so I know I'm going to come across as an idiot. but on the other hand, it looks like the best place to ask this question since I have been unable to find it out anywhere else,I'll try to keep it short too.
I suspect that the oil that I used in my 1988 Toyota Celica turbo has caused undue damage to the engine. I spun a rod bearing. Here's why I think it was the fault of the oil:
I put the oil "Quaker State Semi Synthetic blend for High Horsepower Engines" in the car at the same time as I did some upgrades to the turbo system. It started smoking, so I figured it was due to the upgrades. I played around with it and got it to smoke less, but not completely go away. Then the bearing spun in the journal. I still didnt think it was the oil until my friend changed the oil in his mazda 323.
He got the car to run at our local track that has a single cam 4-cylinder class. He ran it one week, and it ran fine. He changed the oil to the same junk I put in my car, that was the ONLY thing that changed. When we started the car up it smoked a LOT at idle, UNBEARABLY at part throttle and under any kind of load there was an opaque smoke-screen behind the car. we figured rings and valve seals but why did it go when the oil was changed?? well, we heard a similar story from another friend and he swore up and down it was the oil doing it. So we dumped the oil, flushed the engine, and put in 10w40 conventional oil. It smoked for 2 laps on the track at full throttle, and then dissapeared. It's run around 50 laps since then with not a trace of smoke.
What would cause this, because I've never heard of the oil doing that before! My friend is a licensed technician and so is the other guy who told us to change the oil. They can't understand it either.
any help would be great, because i want to know if perhaps quaker state is responsable for my engine damage.
THANKS! Mike
