JIM FROM WILLINGBORO, N.J.: I own a 2008 Dodge pickup with the Hemi engine. I switched to Pennzoil full synthetic oil at 20K miles. The truck now has 40K on it and it’s due for an oil change. I was told that Chrysler would not stand behind the warranty if there were an engine problem because I used full synthetic. Should I switch back, or is it too late?
TOM: Who told you this? The dealer? Your Uncle Charlie who used to work on cars back in the ‘60s? Unless stated specifically in the warranty or owner’s manual, this is false. The Magnuson Moss Warranty Act of 1972 protects against this sort of thing. It states that the manufacturer carries the burden of proof of any failure whatsoever. They must prove that the installation of the aftermarket product caused the problem. If they can’t, then you are covered. Get the facts straight before changing back. By the way, changing between synthetic and conventional oil does no harm to the engine. Success to you.
MAY FROM LANDS END, N.C.: My ‘95 Toyota 4R is flashing an O/D OFF light. Also, I am having a hard time rolling the car after I stop for a red light. Could this be a simple problem? Can I still drive the car in this condition? I am not ready to buy another car yet!
TOM: The light is on because the drivetrain computer sees an anomaly in the system. Have the vehicle scanned for codes to identify the cause and repair it. The fact that the vehicle has a hard time rolling concerns me. It could be that the transfer case is locking up due to an electrical malady. Get it scanned and fixed before you do irreversible damage to the drivetrain. Best to you.
