Funny there is even a thread on this. You drive a car that brand new depending on model can exceed 40k and where you wanna save money is on a oil change that is less then 100 bucks? HAHAH. Thats like spending the dollars and saving the pennies. Take your cheap *** and get a oil change at least when the manual states you should.

LOL! :icon17: Yeah, Reminds me ov all the CHEEEP D00sherz I work w/roll'n $80K+ Euro "performance" sedans, then go and put Wal*MarX oil and cHineez knock off parts on it, to maintain it! LuLz! :icon17:
"It's just the image" or "Image is Perception" they say...:shakes head:

I know how i drive,,,2500 mile oil changes for me-using 5/30 mobil 1 synthetic & K&N HP-1010 oil filter.

Yea funny I'm the same way sitting at the dealer now ,2700 miles later and feel like I did it late , lol . I don't think I've ever even went to 3k in 40 years ! But I'm crazy :)

I use Walmart oil in the Z - 5 quarts of Mobil 1 cost me $23.88 just the other day :twocents:

I use motul every 3000 miles

I'm a 7500 KMS oil change guy, about 46xx miles. Redline oil and K&N filter.

So, what's the sort-of-kind-of verdict here?

Current daily driver w/ low spirited driving in cooler weather driving maybe 500 to 800 miles a week highway @70mph with temps of about 180 to 200 F*, until I get a new daily soon, with oil changes every 5k. Switched to synthetic last oil change. At 100,182 miles/161,227km.

I didn't read any of this thread, but the verdict for anyone trying to figure their change intervals should be to get oil analysis done a few times. Then you will know with far greater precision how long you can go with your choice of oil, driving habits, and conditions in your locale.

:iagree: with everything said here. Contact Blackstone. They will send you a free kit to ship your oil in. Analysis costs $25.

Blackstone got me for $38.00, but i asked for the works-including the TBN (which was 6.9)...been running it hard lately & approaching 90k, so i wanted to test it.
They said to try 5,000mi. on next one; as i normally change every 2500mi.
