Q: What do you think about extended warranties? I have a 1999 Cadillac DeVille (in excellent condition) with 65,000 miles and its extended warranty has expired. I’m looking for an extended warranty. I’ve been online and have found a number of warranties but don’t know which one to purchase. What do you recommend? -- D.R., Alsip

A: D.R., to answer your first question, I generally like the warranties offered from the vehicle manufacturer. But you’ve got to read everything, including the fine print. You need to know what’s covered and what isn’t. You need to know what might cause the issuing agency to not cover a repair. You need to know if there’s a deductible and how much it is. You need to know if the agency you’re thinking about buying from is reputable. Before you buy, contact the Better Business Bureau at 312-832-0500.

Q: I have a 1991 Chevrolet Camaro that is mostly kept in storage. The problem is that the battery keeps going dead. Every three or four months I like to start the engine. I was told that if the vehicle isn’t started often, a trickle charger should be connected to the battery. Well, I even put a trickle charger on the battery and it still goes dead. I’d like to know what I can do to find out what the problem is. -- C.B.

A: C.B., apparently there’s an excessive parasitic drain on the battery, one that the trickle charger can’t keep up with. You have a couple of options. Option 1, take your car to an ASE-certified technician and have them find the excessive amperage draw. Option 2, install a battery disconnect. I have a battery disconnect switch on my R.V. that’s parked in outside storage from November until June. I flip the switch to off in November. In June, I open the hood, flip the switch closed and the engine starts right up.

Q: The message “Stop Engine – Oil Pressure Low” is coming on in my Cadillac Seville STS. If I turn the engine off and then back on, the message is gone. It will take a while before the message reappears. When it does reappear, I simply shut the engine off again and restart it. What do you think is wrong? -- W.S., Tinley Park

A: W.S., the oil pressure sensor or its wiring could be faulty. A technician should also check your engine’s oil pressure, just to be safe. If you operate the engine with low oil pressure, premature wear and/or damage may result. You should have your Cadillac checked out as soon as possible so you avoid any further damage.

Q: I read your column about oil consumption and I agree with your reader that one quart per one-thousand miles of driving is excessive. Do you have a list of various engines that Chrysler produces that burn excessive oil? I work for a funeral home and we purchased a Town & Country with the 3.3-liter V6. I’m concerned if this is one of the engines that burns oil. Please reply. -- J.O., Oak Lawn

A: J.O., there is no such list. I would only recommend that your employer follow the manufacturer’s recommendations for maintenance. If during the warranty period you feel that the engine is consuming oil excessively, take it to the dealer for an inspection and/or contact the manufacturer.
