Differential heater

[Alex Denysenko]

have heated the gear oil several times never saw a thing out of it
so we just use the good gear oil and that does the trick

My friend's recently sold Pro Stocker had an oil tank/pan heater screwed into a welded-in bung in the back of the rear end housing. The cord was zip-tied to the left wheelie bar so it was easy to plug in to warm up the gear lube before each round. I thought about adding one to mine. Easy to weld the bung to the rear cover of my 12 bolt. Just use it for tough heads ups, class, etc.

Heard of guys running Dexron ATF for gear lube (One guy said "all the time"). Not sure about that deal. I'm too old to weld up the gears in the lights and go for a ride. LOL

Use a light weight synthetic rear gear lube.

Good reference point - FWD cars use ATF to lube the differential......

For that matter you could probably completely drain the rear-end for one pass without damage.

This is the stuff that I was envisioning, "outside of the box" keep it coming

I helped on a Comp car years ago, where ATF was tried in the diff.
It ran E/SM at the time (old format) and right on the record.
It was losing nearly .10 each pass.
After 3 qualifying attempts, we could hardly push the car.
Tore it up pretty good...
Used gear oil from then on.

That ^^^^ doesn't really surprise me. I never had the nerve to try it. I appreciate hearing that. The guy talking about running it all the time has a slow et bracket car. Like 13 seconds. He never mentiond testing it, he was just sure it had to be "worth something".

I ran it half full of gear lube for a couple of weeks. (Listening to the wrong guy) I had changed something else at the same time (should know better by now) When I filled it back up I picked up a good half a MPH with it topped off.
