Looks like someone has an addiction to Accuracy International stocks! Or are they AI built rifles? Either way, nice collection!

Believe me, I am. It honestly is a good cleaner, but I think it kind of sucks as a lubricant. Way over priced as well.

I've been using FrogLube for a while. I really like it in the summer, but absolutely hate it in the winter. It turns into a sticky paste when cold. It gets so thick that the BCG is hard to move in the upper receiver. I've been switching back to Hoppes oil lately in all my guns.

Either one will work. You just need something thin enough to get into the lash adjusters. The ATF has worked well on several engines, so I have no doubts about it. I've seen some dealers use solvents, but I don't like that as you won't get all of the solvent out before the final oil change. You...

The 2.2 was a good engine. Very low tech and reliable. They did have some headgasket issues, so check for coolant leaks, especially on the end of the head near the transmission. My wife had a 97. We got rid of it with 190k and it still ran and drove fine. I used 5w30 maxlife in it every time.

It really doesn't have a whole lot of detergent (less than motor oil afaik). The real point of it, in this situation, is to penatrate the small oil passages in the lash adjusters and carry away the dirt or sludge. It's also cheap, and cheap is good since it's getting drained and discarded after...

The ATF does have detergents, and it cleans sludge good. ATF is generally very "thin" and flows well, which is what you want to work its way into the hydraulic lash adjusters (lifters). You could also substitute a thin, cheap motor oil. Since the engine is being run for a few minutes under...

This is how we do it at the dealership: Change oil and use a cheap ATF instead of motor oil. Valvoline maxlife ATF works well for this. Use a cheap filter. Run the engine at 2500-3000 rpm for about 10 minutes. Change the oil and filter again using a good filter and a high detergent oil. Rotella...

Thanks, that's good to know. High rpm oil pressure is around 70psi.

I have a 98 dodge neon I use for autocross and track days only. I typically run redline 5w40 or 10w40, but I get free cases of M1 0w40. is it up to the task? Oil temps run 200-230 degrees. Hot oil pressure at idle is around 35 psi in the block and 20 psi in the head. The car has a built high...
