Oil Change Help

[trini_gsr]

why do you say this? do you get your oil tested? do you have any information to back this up or just going on what other people say and talk about.

i've never personally done it but i've read up a good bit on the subject (mostly on bobistheoilguy.com) and experimented with lots of oil weights and brands before going with what i use now. i also have friends with very similar setups (daily driven boosted hondas) do the same and get their oil tested and we've discussed the results. this is my 2nd boosted honda and it's been almost 4 yrs and damn near 70k daily-driven miles on this particular motor...it sees full boost almost every day and it is still running strong. so i do know a LITTLE about what i am talking about

i know what trying to get at and you're mostly right...now i'm not a mechanic but i am speaking from my personal experience. maybe my mind is playing tricks on me but honestly i can usually notice a difference (even if it's slight) in my car's performance after i've run the oil for 3k or so miles. i know when it's time for a change without even having to check the odometer.

you do know oil changes before AND after a trim tune isnt buying you anything right. and when it turns black still doesnt mean its bad yet.

truth. i ran a lil long on my last oil change and within 1k miles its dark again. lol.

thank you for not just posting blah blah blah... but actually what YOU have done and not hearsay. but i do have to say something about your so called power loss. oil become THINNER with use, not thicker. and yes i know friction goes up with that particulates of dirt and what not in it. but the gas from blow by thins it out. hmm... i guess its kinda funny. how that works though.

true i have changed oil in 500 miles on a old motor that usually get oil changes every 3k for its whole life. and after 500 miles it was pretty much black. you cant really test it out by doing multiple oil changes right after each other with almost no run time between. just to help get out ALL the old oil. since you would have to tear down the motor to get all of it. or just do many oil change/flushes.
