Re: When do you change your oil?
 

I agree with feedback from F5 and NewHummerGuy on the oil monitoring system and I am doing my oil changes at intervals closer to 8000 miles + based on system.

250,000 miles at 40 bucks a change for synthetic maybe more. Im just guessing cause firestone is more than that without the coupon. If you change your oil every 6,000 miles for 250,000 you could've bought an engine and a transmission anyway. Plus they will probly be cheaper to get a rebuilt one by then.

This is interesting
Make sure you guys read the 3k mile myth and the dark oil myth on the bottom

Re: When do you change your oil?
 

My H3, will be a year old in April. Up to this point I have been changing my oil every three months, regardless.
Now that the first year is almost done, I think the motor is pretty well broken in. I only have around 7600 miles on the truck. I will do one more three month oil change in April, have the air filter and wipers changed out as well.
Then...from April on forward,
The PCM will be the oil change indicator.

Decent article but...

"There are still vehicles that need 3K oil changes, but it's not because the oil goes bad after 3K miles. One example is the Saturn S series. These vehicles have a timing chain system that is very sensitive to clean oil because oil pressure is used as hydraulic fluid to ratchet up the timing chain tensioner. If varnish forms in the timing chain tensioner bore then this system can fail and the chain will become loose and eventually break. Dealers have gone as far as tearing out the normal service schedule (6000 miles) and leaving only the severe service schedule. If an engine is destroyed by a failed timing chain while under warranty, then the dealer will legitimately request evidence of oil changes from the owner. Unfortunately this problem usually won't manifest itself during the warranty period."

True for first two years of the S-series; however, after that there was no big problem with the oil passages and varnishing for lubricating the timing chain. Also, no dealer was able to void a warranty if the customer had the oil changed at 6K. NO dealer can VOID a warranty, only Saturn corp could void a warranty, and we NEVER voided a warranty for changing oil at the recommeneded interval.
Hell, we knew it was a problem, and even cars out of warranty were covered if the customer called, or the dealer called for 'em.

"Instead of making motor oil with the conventional petroleum base, "true" synthetic oil base stocks are artificially synthesized. ("Commercial" synthetic oils are in fact Group III mineral base oils.) "

Mobil 1 and one of the grades of Amsoil are Group IV syntethic; there might be others.
