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?

 

When I used to run synthetic (not in my truck) I did the same thing ran it 6,000 miles and changed the filter every 3,000.

With DINO I stick to the every 3,000 or 3 months. Even if I have only put 1,000 miles on.

 

I always change both the oil and filter (including synthetic) every 3,000mi or ever 3 months, whichever comes first.

 

Right now I'm using rotella T6 5W40 synthetic and Toyota filters and I always change it at 3K miles give or take a couple hundred as well, cheap insurance is how I look at it. Plus the rotella is cheap enough anyways so I don't really feel like I'm wasting anything.

 

You change your oil to get the moisture and grit out of the engine. The biggest one is moisture, being that can destroy your internals the quickest.

What ever oil you use, syn or dino, just change it every three months or 3,000 miles. I am always a big beliver that over changing the oil is the best thing for a motor.
