Sajeev, here is a possible line of discussion: ethanol fuel. It’s hard to find straight gasoline now and impossible in the more populous counties of Texas. E15 is around the corner. My old D21 is still running strong at over 200K (previously discussed here and here —SM) but I fear that adding E15 might be the kiss of death for its early ’90s system.

Additives, alternatives and a point of discussion?

Hi Sajeev,

I do a more through job at the time of purchase, but every year after I do a drain/refill on the radiator and replace some transmission fluid by using my fluid extractor to vacuum up as much ATF as possible through the dipstick tube.

I know that I’m not getting all the fluids exchanged this way, but my question is how much of a positive impact is this regiment actually having on my cars? Am I just wasting my time? I haven’t suffered a mechanical failure since I started doing this, but I don’t know if that proves much.

Keep in mind that the vehicles I tend to own are 20 to 30 years old.
