i know this has been a long time discussion over many forums and asked different ways sorry if its a repeat, i dont drive nearly as much as i use to (maybe 8k miles a year) i use mobile 5w-30 and a factory oil filter. my main question is about my oil filter and whats it doing over time. i totally belive in the 6 month syn oil change interval or even higher mileage but as long as i can rack up the miles in 6 months. currently i did my last oil chnage dec 4th and have only driven 4500 miles im sure the oil is ok but im worried the filter may not filter be 100% up to par i may start changing the filter every 3k miles and do oil every 6k miles as long as continue to drive this little. Does the oil life monitior actually "record/keep track of" cold starts, intown driving, driving habits such as reving stop and go and long idol periods in traffic? I know a 5$ dollar filter every 6-8 months would pretty much answer my question here just wanted some of your opinions also thanks?

 

i believe the oil life monitor just reads by how long your care is on bc last year i drove 2k and it was down to 25% so idk could just be my car

 

i go every 5k but im fully synthetic. idk about you. youre "good" til 10k or more says the oil manufacturers but i say 5k.

 

I tested this on someone else's car recently. The oil went 14k miles before the oil life reminder was at 5%. It's build off how many times the cams turn and habits and a bunch of **** that goes into it. Basically if it says 0 change it. If you still have 5% the engine goes boom gm will still cover it cause your still within limits. But also keep in mind this is an oil life "reminder" not a always go by me bs. Mainly for women just like tire pressure sensors. Woman can't reset either so they get annoyed and take it in. Most should I say

 

^Ya im full synthetic also i change around 4-5k

 

oil life monitor tracks temperature and RPMs

 

i change mine with mobile 1 around every 5k, is there any oil better for the car? or is mobile 1 all it should ever need?

 

Don't ask that cause you will cause all sorts of stuff on here and it won't be good

 

i changed mine every 10, i thought most people change regular oil every 4k nowadays so i dont know why someone would change synthetic oil at 5k

 

5k because it lasts me a good long while because i dont drive it all that often so its good to get the old oil out.

and I use Royal Purple... Mobil 1 is also fantastic. NOT STARTING that one here!

if you really want to know EVERYTHING about oil go to bobistheoilguy.com

 

Have y'all ever wondered why they put 5k or 3 months? Think about it the oil at the store doesn't have expiration dates on the bottles

 

because when u open the bottle and put it in your car it is exposed to moisture and other things

 

Gm and mobil 1 state the oil should be changed at least time a year no matter how little you drive

 

U mean at least 1 time

 

Mobile 1 Full Synthetic 5w-30 every 6K miles. Pretty much when he oil life indicator hits 25%
