Lol at this thread...
I want to add some things about my lack of burn off experience with AMSOIL. I went from driving 18k a year to about 25-30k a year, so my amount of driving increased...therefore, I am putting my miles on the car in an equivalent time period. Furthermore, I am doing so while starting the car less cold and putting more miles on it between start-ups.
What this means, to me, is that where previously I may have driven 6-7 miles per cold start-up, I am now driving 10 miles per cold start-up (numbers used as example only). So the chance for the oil to be lost as a result of in-adequate sealing on cold-start up has lessened...this may be part of the reason my burn-off has gone down so completely.
Pablo - I had a 1995 Volvo 850 turbo. When I bought it in 04 with 113k miles on it, the oil that came off the dipstick (after the car had been sitting) had literal grit in it. Not only was it black, but it looked like it had been collecting dirt. I, foolishly, ran a cycle of gunk motor flush through the engine. Nothing bad happened, and the next oil was must cleaner. I tried a variety of oils over the next 28k miles of ownership, and I found that two oils resulted in the best feel:
A synthetic blend (I bought it on a whim, heavily discounted, Castrol Syntec 5w30) and a 5w40 full synthetic.
My thought was that those robust volvo 5-cylinders tend to run smoother with a heavier weight oil in them.
Regardless, that turbo engine was a tank. [censored], I even drove it for a few miles after the trans hose to the trans oil cooler came out, spilled all the trans fluid, and with the transmission slipping insanely. Filled it back up with el-cheapo trans fluid and off we went
