Me thinks every 6 months or until lifters tick, oil is black, or like 6 track days or so.

My buddies with superchargers all get fuel contamination supposedly, so they run dino oil and change every 3 track days. (They also think pouring tolueline instead of retarding spark get the job done...lol)


The m.net answers are funny. I don't see any reason whyI should change the oil until pressure drops, the oil is black, lifters tick, or something more intelligent like an oil analysis.

 

oil is cheap compared to motors. i'd change it after every race weekend. I probably would still only change the filter 2 times per year though.

 

That would be 12-20 oil changes per year for me.


Maybe I'll just get an oil analysis.

 

buy some ******* oil, don't be gay.

 

i wouldn't bother, i'd use synthetic and change it every 3000 miles. i've yet to see a motor go because of lack of changing oil. The worst i've seen is at work a customer brought in their ML320 because the oil light came on. there was plenty of oil in there so the tech pulled the oil level sensor thinking it was bad and sludge came out with it. Pulled the pan and you could scoop handfuls of sludge out of it. We cleaned it out real nice, changed the oil, ran it for a while, changed the oil again and it's been fine since. The oil wasn't changed in 40K miles and was done at a jiffy lube or something like that with crap oil.

so i say run synthetic, change it every 3-5k and you shouldn't have any problems.

 

Run it till you hear lifte tick or it's just black. I go around 10K on dino between changes. Right now 11.5K since mobile 1 Clean 5K and I've ran it 8 times at the track and used 6 bottles worth of nitrous. I did spin a new filter on around 8K, but the oil hasn't been changed yet. I got to drive 260 miles home tommorow, and I'm not planning on changing the oil yet, it's still got some life in it. I couldn't see changing it every time you race though, that seems unnecessary to me.

 

I go 3000 miles tops on synthetic, but that's probably overkill. I'd change it after every track day if I were intelligent, but my "track days" are usually 2-driver two-day weekends, so around 4 track days on an oil change.

 

I'm seriously thinking about buying some amsoil, and changing it every 6 months, or until it looks like it needs it...or something else tells me to change it.

 

That's what I would do. I'd suggest something like 5W50, really helped my car with lifter tick after running it really hard.

 

 

when i used to take the corolla out to a drift event, (its gone now but anyway) i used to change the oil before every track event. Drift events, youre constantly tapping the rev limiter, so i would suppose its a better idea, but then again, i was just using regular dino oil... the 4AGE doesnt have the need (IMO) the use of synthetics. After a track event, i would just check the oil and see how well it fared, and drive around on it until the next one, or when i accumulate miles; whichever comes first.

 

Filters are the cheapest part of an oil change. . . why don't you change those every time you change the oil?

I don't really keep track of mileage for oil-change, I just check it often and change it when the lifters click.
