does anyone besides me run lucas in their truck? what about trans fluid? i was thinking royal purple? any ideas?

 

u will note a diffrence
i run royal purple w/ lucas for the engine and lucas on the tran i also use the lucas for the gas tank
it really saves gas

 

If you are concerned about warranty, don't run any additives. My stepdaughter sprung a leak in her (rebuilt) tranny in her minivan, and Chrysler specifically told her NOT to put any Lucas in it, only use spec fluid till she could get it in for warranty repair.
