my 2cents..every vehicle ive had ive run lucas oil stabilizer, fuel treatment, power steering treatment, red tacky (for greasable shackles and such) and their gear oil for trasfercases, chunks, and such... and tranny additive.it has kept great compression on my wifes yukon and internal parts in great shape at 200k(knock wood) and has worked well on my fords and jeeps. as for my yota ive used the fuel treatment with a little notice of better response, but havent added the others yet...ive had it for bout 6 mos and waitin to see what the experts on here say bout mixin all the additives with yotas.

 

Lucus is the best additive for just about anything. The Power Steering needs auto tranny fluid, PS fluid creates leaks in our stearing kit- like mine. However, I just put straight lucus PS stop leak and it's fine after a couple refills. Even though it's running on nothing but Lucus stop leak.

Yes acetone, try it out. def cleans out the injectors...
