Iv been on b100 for a year now and 50/50 befor that without any problems. I switched to amsoil 5-40 w/a remote filter - ran fine for 8K then the LOP light went off. changed oil but 1 month later LOP light was back on. So I drained the bio, took off the 5"turbo back, reset to stock, ran 4 tanks of dino and took it to the stealership. They said that 5-40 was not good enough so I changed back from synth to 15-40 > no light Now 5 weeks later LOP light is back. The other thing the stealership said was that I cant run b100 acording to GM, and gave me a bulletin saying so, of course I said "whats b100?" The bulliten said there would be too much blow-by and would thin out the oil. Too much blow-by, with 30K I DONT THINK SO. If Ive got that much blow-by then this engine is a piece of........!! Both samples of oil sent to amsoil came back low viscosity but with -0- fuel in the oil
anyway
thoughts?
If fuel is getting into the oil & thinning it then the level would have to rise.
And if it is how did it getting in there cause I dont buy the blow-by crap?
Could it be the idiot light sensor? but not with fresh oil
What was the "tell" that gave the stealership the idea that I was running bio?
By the way the guage never seems to drop below 25 lbs?.
Thanks for listening
