I put my first batch of RP in at 4500 miles and I am now at 10,059..Is it about time to replace the old with some new??

Also how often do you need to replace transmission fluid?

 

I replace my oil every 2500 no matter what.

 

ok but what is normal...

 

do it every 3000 miles just like any car and you will be fine

 

but synthetic is supposed to last longer..

 

I change my amsoil every 9-10k miles or so. Amsoil recommends 12k miles for severe use, and 25k for casual use or 1 year whatever comes first. My car has 42k miles and has had this routine since 12k miles, and no problems yet.

 

i use royal purple and like i said i change it every 3000

 

can you use RP for 8-10k miles?

 

I change mine with synthetic oil every 3,750 miles

 

I run mobil1 and change mine every 5-7k w/ city driving. I think it's a waste of money changing synthetic oil every 3k unless your boosting. Oil is everything on a turbo engine

 

+1, burnoff is a *****! Not saying I suffer from it.... But I change and refill before any oil can burn off..... Safe is better than sorry.....

 

I run mobil1 and change it every 3,000 miles strictly. Will be switching to German Castrol 0W30 (GC) next oil change... supposidly autozone has it, but i still have to find one that carries it.

 

I change out my RP every 3K miles...pretty standard for most people. You'll find plenty of people who hate on those who change this frequently...don't know why they throw a fit...YOU CAN NEVER GO WRONG WITH FRESH OIL. Do what you have a peace with...good luck!!

 

A good synthetic oil should provide decent protection for up to 10k miles. Most people that are replacing synthetic oil every 3k miles on a NA engine are just wasting perfectly good oil. I would change synthetic oil in at least 5k mile intervals. I think a good synthetic schedule is 5-7k mile intervals. Just make sure to check your oil every now and then... as that may allow you to form your own opinion on how often you may or may not need to change your oil. Every car is different. Naturally our cars have a tendency to burn a bit of oil so keep that in mind also.

 

Same here... I use AmsOil 5W30

 

i change my oil every 3k, but i have no other choice. everytime i go to change it, the oil level is down to 2 1/2 qts.

my cars is seriously burning oil!!!

 

I change mine every 5k and haven't had any issues...

 

For those of you that change your oil every 3kish miles, maybe take a quick read:

what mobil 1 oil filter do i need, i forgot what i bought last time!

 

If I'm not mistaken, a few people here how gotten an analysis of their oil at different intervals and have gotten pretty good results. I think Wired24/7 was one of them. I can't remember what the interval was but it was over 5K for sure.
