Oil Change Intervals 2001-2005

[ncelk]

Want some feedback from you guys.

I am currently running Mobil 1 0w30 and the base FFS kit.

I am now running OCI of 3000-3500. I am thinking about going to 5k.

What are you guys running?

0-30M1 is an excellent oil. I ran it for a long time. After the FFS(115 pulley) I bumped to the M1 0-40. 5K OCI is a stroll in the park
for any of the M1 products. If you start using a little more oil which is normal after going FI try the 0-40. I'll be sending off a sample around 6K. I expect they'll tell me to take it out to 7K.

Went SC about 18 months ago, put about 8k on it since then.

No oil burning at all (knocks wood). But I am pretty easy on it except for some boosted fun once in a while.........

I run 5w30 Mobil1 and change oil when I start to get lifter tick. This is somewhere in the 5K range.

Otherwise, I just top it off when it gets low. I guess I am using about 1/2 qt about every 1000 miles. Not sure where it goes. No evidence of leaking or burning. I think it just evaporates...

I run moble reg dyno oil 5w30 and change it every 3 to 4k no more. I think if it as cheap ins. I use to use mobil 1 sysn, oil found for the cost no more protection then the other car which has had dyno oil for its whole life.
the turbo uses 5w20 dyno oil.

I have used the Mobil One 0w-30 and liked the way the car ran, however, I have now paid to have two car's rear main seal and oil pan gasket replaced. I cannot help but wonder if the thin oil didn't make the leak worse.

I now use only M1 10w-30 with annual changes (under 5,000 miles). May try 0w-40 though.
