See! This is why i love this website and you all
The reason, or reasons i wanna try/use MMO is because for one, ive simply always wanted too. never did, just once, too say i did it,and the engine didnt KO..
the other reason, is because i belive my rngs are bad or something. I inherited this 98 corolla from my father after he passed, 2007. sat in driveway for some 4/5 years. Only had like 43,000 miles on it. my father used too go too our local jiffy lube..they used castrol,dont remember the filter. my father always went by time, or squeezing mileage in even if it was past oil change time. and thiers alot of stop n go traffic here.
So 2012 or so, puta new fram air filter in, did oil change flush, new battery. i still remember that day with roomate,musta been may that year, we discovered horet coming out of the dash vent deriver side, no alot, but a few.small hornet nest under the driver side febder lol.
well since then, ive done 3 month oil changes.accumulating 800-1500miles in 3 months. the oil was thick, black, looked molassis kinda. using dino 10w30's. under oil cap, instead of metal, it was like somone cooked a gravy roast that burnt. ver time doing reg oil changes it has dissapered. now have 73,000miles on it. i have uses havoline 5w30 and 10w30 i bought on walmart clearance10 years ago, (read here about its high moly contebt! abd in 3 onths, like last year,2 quarts wwould be missing! no leaks...apparenty it burned out the tailpipe. i have changedthe PVC valve as well, as of 2 years ago, dealer pcv valve..and prob has 10,000 miles on it.
so laast year added 10w30 havoline august. amonth goes by, and i dunno, uptoo 700mile..dipstick was 2 quarts low! added 2 quartsmobil super synthetic, 10w30. it mostly held for another1500 milesor so. but levelstrated goin down. so chnaged oil yesterday, putting 2 16.9bottles of rislone concentrate in drive 100 miles. gunna use theold bottles of havoline as a flush, then use PYB 5w30. but replace a quart with MMO...clean mop up the engine, so too speak.
the oil yesterday was thickish, and blacker than midnite.itlooked like itwas asking too be recycled.
this is why im wanting to try use MMO. im assuming the rings with these smaller pistons toyota knew/knows about are coked, buthoping its not worse than that. ive raed from quite a few on toyotnation and corollaland, theyde only use a full synthetic in these engines. im a dino oil person though lol...so that kinda conflicts.
