hmm, nice info.

 

ohh, ye I have checked the mobil website and I got that clean500 is conventional oil, like castrol syntec. and the clean7500 is syntetic blend. the clean high milage is conventional blend. the mobil1 is syntetic and mobil1 extended performance is syntetic with extra cleaners.

well I will probably get, mobil1 0w-40 or 5w-40 or mobil1extended 10w-40

Basically I have now cSt @ 100C 10.6 thats on 5w-30 The next level is around 14.

so any oil with an end of 40 is good for me. I wana still higher presure.

the 0W-40 cSt @ 40C is 80 while 5W-40 has 102

Note: the lower the Cst number the more freally it flows. our engines have hydralic lifters the lower the cSt the better they will fill up.

 

what I noticed is that in the morning I dont even hear the lifters any more. They usually made some nois then after like 30sec disapear.

 

Ok so then my 3 seconds of lifter noise on morning startup isn't a terrible thing then?

I'm at 147,000 on my 1987 2.3 liter naturally aspirated 5 cylinder.

Because I do autocross (first time in this car this Sunday actually), I really want to clean the oil passages, change out the oil with something a little thicker (10/50 maybe), and swap out the oil pump for something with a little more pumping pressure. I may end up simply putting on an oil cooler though as too much oil pressure can be a bad thing. I had one lifter giving me a little bit of a hard time after the 3rd the 4th run for a minute while the oil cooled.

 

the noise is a terible thing, yours just isnt too bad yet
what oil are you using now?
most of the times, if I remember corectly all you do is just get new lifters, or lower viscocity oil grade.
