Oil change...plus

[07Burb]

I do my oil change once a year do to the fact I only put about 5k a year on it

Doesn't oil lose some of it's lubricating properties (or however you wanna put that) over time, though. I only drive my '77 MAYBE 2,000 miles per year and I change it every fall and spring. Granted, it's a 350 crate motor which is MUCH different from the LS based motors but still...

I believe it does not to sure but i do check the oil level quite often and color of oil which always looks fresh and every oil change I flush motor and add Lucas stabilizer with 5w-30 mobile 1 fully synthetic

I change my oil when it says 50% oil life on the DIC

It really depends on driving style. My wife, nor I, kill the right pedal on take-off. In town driving is VERY minimal, as we usually use the Explorer, since it's better on in town MPG than the Tahoe is. It's used for twice a month trips to Ohio and back, totaling roughly 575 miles round trip, all highway at no faster than 66 MPH.

Like I said...it could have waited another month or so...

We drive pretty conservative but we do drive a LOT in town which is quite a bit harder than traveling mostly highway. That's another reason why I do it at 50%.

That makes sense burb when I do drive it's a Guaranteed 30min one way trip all highway . I knew a lady that drove her car once a month and change the oil once a year but when she drove it was like a 10min trip to the bank or grocery store which I believe it's bad for the motor since its not getting a chance to run for long periods of time and dissolve what ever build up the oil has caused. In my case I make sure it's a good distance before pulling it out the garage.

every 5000 with synthetic... dont even have to jack the truck up just roll under it. takes 20 mins if you let it drain 10 if you dont feel like it

So Burb, are you asking if motor oil has an expiration date?? Do you really want to ask that on this forum or would you like to take back the question??

i oil life on dic is 6000 mile intervals, so 50% is 3000 miles. thats what i shoot for but i dont feel bad or get in a huge hurry it its alittle late. but if you ask a shot, they will tell you oil last 3 months or 3000 miles, whichever comes first.

I say maintenance is cheap and good protection. Never had an issue with doing it and for me it is every 3 months or 3,000 miles which ever comes first. Remember gas now days starts to breakdown and varnish in 14 days. And that is petroleum based just like oil. I say it is cheap and easy for me to drop my truck off and have my shop do it and also they can give it the once over when they rotate my KM2's which I do every oil change for maximum life.
