For those of you that change your own earl. I found this and from what Ive been told it works REALLY well.

Works very well. Had one on my previous car. I now let my tuner change my oil and use it as a chance for him to look at the car every 3k miles.

 

I take mine to Rob every 2500miles

 

I was planning on doing it every 3000 miles, but I did the first at 2800. Never made it to oil change #2

 

i do mine every 2500 miles like said above and i of course change the filter as well. btw my oil looks almost as clear as the day i put it in.

 

Every 2500-3000 miles...

 

3000 miles

 

Always did mine every 2000 miles, I didnt want to take any chances. If the engine begins to consume oil faster than usual I didnt trust the dipstick to tell me.

 

About every 2500 miles +/- 200-300miles and its usually pretty dark.

I thought about one of those quick drain plugs but figured loosening (1) 14mm bolt once every other month wasn't to much of a hassle. Considering I like to go under the car checking everything out about that often anyway.

 

I run to about 5000 miles. I do a filter change at 2500 miles and top off from their. I use Redline and have had the oil analyzed a few times and 5k is about the limit.

 

i had the junk on my previous car (99 Prelude) and it sucks. doesnt flow out fast enough. i returned it the next day.

 

2500-3000 miles as well, but mostly at 2500 If i am not lazy!!!

 

I change oil and filter every 3k.
