Oil Change Intervals

[dletm08]

I used to change my oil religiously every 3K. back in 2003 I stopped and started doing it every 4-5 depending on how black the oil was.

The trucks I drive at work are all diesel and are on oil changes every 5K, but sometimes they go 10K or more if our mechanic is backed up, or too busy catching some Zs down in the garage. They say diesel engines are dirty and need oil changes more frequently, so I figured if our trucks are still going strong on that oil, then my gasoline car ought to be okay for a lot longer than 3K on the oil change.

just wondering what all of you guys do your oil changes at.

yeah i think the whole 3k oil change thing is a scam. The garages then get you in there and do their "courtesy check" and find a bunch of other crap to sell you while you are there. I used to work at firestone about 5 years ago. I did mostly tires and oil changes. Firestone are a bunch of crooks.
