if you are burning oil, but know that your car is running well, read this. if not read it anyway. i posted this on the *other* forum, but as usual, the 3rd gen section is more like a kiddy lounge and offers little to no assistance. usually seeing topics like rx7 vs. supra and check out this rice car. that is why i am here. guys, do not make me eat my words now that i am here. i like advice and real support. all of you guys that i know from over there are here. i trust yall. guys like jspec, rikki, vr6, fd3b.., and a few others.



my findings with oil usage

i have been doing a study of oil usage in my car for the past 4-5 months, and i think that what you will find could be useful for you all. however, everyone's opinion will differ, but you will know whick way that i lean after this write up....



well, after deciding that 600-800 miles was too much for my car to be burning a quart to a quart and a half of oil, i decided to experiment.



here is what i have found.



jackson, ms avg temp since may ~85degrees in the day.

9500 miles logged on rebuild since 5-21-02



mobil 1 15-50 synthetic: burned AT LEAST 1qt. every ~950mi.

valvoline 20-50 synthetic: burned AT LEAST 1qt. every ~750-800mi.

amsoil 20-50 race syn.: burned AT LEAST 1qt. every ~800mi.



valvoline regular mineral oil 20-50 : burned LESS than 1qt over a 1400 mile period. oil still looked good, but i still change it every 2200-3000 miles...



mobil 1 20-50 regular : burned less than 1qt as well, under the sam circumstances as the valvoline.



i chose the valvoline because cam at pettit put it in my car after the new engine was installed and i trust his prefrences.



i definately know that the synthetice that heve gone into my car have all burned more rapidly than the regular types of oil. each one of these tests have been closely watched and documented. i decided to try this out because i simply got tired of seeing the oil light come on while halfway home on the interstate or sitting in traffic. these things concern me because my engine life sconcerns me as well.



i understand the ash content variables as well, and can tell you that the regular vs. the synthetic test i have done has its differences.



synthetic seems to burn slightly cleaner, but the sear amount that the car was going through as compare to the regular oil was proof enough for me.



i am going to stay with the regular oil for now. ****. i have been using the syn. oils for a few years now, but have a new outlook now.



synthetics are thinner, and yes can seep into the small areas better, but what about during the super high heat runs and cool downs. this is where the regular oil makes me more secure.



heat some up in a pan at the house. a side by side comparison will show you what i have seen and hopefully you will see my reasoning.



well that is it for now, but i am sure that i have other things that i can add but am simply forgetting....



add in your thoughts and reasoning as well. i know that this is an age old battle, full of opinions and differences, so lets hear them.

Excellent write up Louis. I'll give this thread 1 month, then I'll move it to the FAQ 3rd Gen Section for future reference.

thanks man. i talked to ryan the other night, and was gonna pm you.



but fock it...



when i finished the NS on my car, i left the solenoids in and did not opt for doing the resistors.



however it may be, when i cranked the car, my idle, which used to be around 1050rpms, is now @ ~1600.



WTF.... i touched NOTHING on the TB, that i remember. it should not have affected the idle right....

Push your brake pedal in. If it's REALLY hard to push, then you forgot to put your boost assist hose on. The one from the UIM to the brake booster. I've done that before too.

r_xplicit

i do not think that i forgot that one. is it the one that is on the left of the UIM. right off of the runners on th efirewall side?



either way, my pedal is ok....



however it IS really low. but it is due to the face that a previous owner of the car never bolted in the top mounting bolt on the brake pedal frame brace....

Hmmm...something else then...Let me think for a bit.

r_xplicit

cool. ryan said something abou the hot wax rod. uhhh, i never remember messing with anything.



now HE said that it is adjustable by a screw right over the oil filter area. true? i did tell him that i adjusted all of the screws in some way or another, with no change at all.



i did not really do anything to the car to make the idle go so high, so i am at a loss.



also on another note, the accelerator pedal is very still. i think that the cable is too short, not too tight, but too short. i might have to replace it.



and one more thing. when the TB was off of the car during the NS conversion, i noticed that if you move the throttle thingy that the cables attach to, it gets slightly stuck, as if there is something catching the butterflies.



weird....
