Keep changing the oil every month using valvoline synthetic blend or should I use full synthetic and change it every two months??? Keep in mind I am a maintenance-o-holic. Just wondering what you all think I should do.

I think that'* a bit extreme, members here are going farther and farther with synthetic, many are working on 7k miles now for changes. It is still perfect after those times too.

I'd say overkill unless you are doing 2500-3000K miles a month :?

As long as its clear...there is no real need to change IMO

Alot of people think I am nuts for changing the oil so often. I got into the habbit of changing it the middle of every month. I dont mind doing it though. I know my internals are spotless . I was thinking today though that if I switched to fully synthetic and changed it every two months I would have added protection from the synthetic and still have a clean engine and good piece of mind. I am undecided though in if I should do that or keep to what I have been doing. I would change my oil with fully syn. every month as well, but I and gots the funds for that.

I average 1200 to 2000 miles a month.

This friday when I put my trans cooler on will be the 3rd time I changed the trans fluid in the 3 months I owned the car. I dont plan to change that again though till after next summer.

My caravan had 190,000 miles on it, if it wasn't for my over-maintenance ways I dont think it would still be going. (some poor sucker in cleveland oh. has that now)

Unless those miles are stop and go (which with that milage i doubt they are) you're changing it too much. Same with the tranny fluid, i'm not sure, but don't these lubricants kinda 'break in' first?

I know I know. But still, I just like the fact that the oils always clean, kinda like I like the fact when I'm wearing clean underwear, you know, Its a good feeling.

If this gives you "piece of mind" than go with Full Syn every other month. Personally I think this is over kill but whatever "floats your boat" is best for you!

lol its your money change it everyday if you want, i bet come 200,000 miles your 3.8 will still be in EXCELLENT condition, i change mine every 3 months, next oil change im going to full synthetic...no leaks at present i wonder about the sythetic causing leakes...also i use Quaker State higher mileage.

I hope by 300,000 it will still be in excellent shape. I guess 200,000 is good too. Actually when the engine itself has 200,000 miles on it the car will have 300000 miles on it. I think the engine should at least outlast the car.
