Ok, the pinging isn't all gone. What gives?

[ryan roopnarine]

the book thing probably says something about high rpms, but i think that more likely it gives somewhat non intuitive tips, like to use one can of the 44, and then use another upon the next tank of gas, or perhaps it has instructions on how to do the induction service winfred outlines.. i think i've seen the book before, and its along the lines of what i describe.

my only gripe with the stuff thusfar is that i guess it has worked its way into my oil, and is making me consume about 1/10 of a quart per 400 miles, whereas my car doesn't normally use more than 3/4 quart between 6k oil changes. techron never made the oil go away like this, and im contemplating doing an oil change if consumption keeps up, and uses more than 2 quarts before 6k.

BTW, I found an online store that was selling a $9 book on how to run your engine with 44K for best results. I assume it's the high RPMs as Warren mentioned, no?

cleaning until the last tank of gas just before an oil change, then drive that tank with the cleaner in it, refill and change the oil right away...

I am suggesting ITALIAN TUNEUPS whenever it starts. I did mine Sunday. Only took about less than a minute of sustained 5500 RPM on the Freeway. Now it's all better again. I think M30s are prone to picking up carbon deposits. Auto will be worst because less likelyhood you will wind high revs very often


QUOTE=BennyM]So I said that after 2 tanks of techron, the pinging had disappeared. And it did, for a week. Now it comes back intermittently, and usually more subtly. I think it's relative to outside temperature. It wasn't noticeable on Wed with 90 F, but was on Thurs with 40 F.

Anyway, how many consecutive tanks can I fill with techron?

And when I change my oil later this week, will that get rid of the crud that's causing the occasional ping? Also, I'm gonna try the 0W40 instead of the 15W50 this time.

Thanks.
