My owner's manual for my 2004 Classic recommends SAE 5W-30 engine oil. I wouldn't add any oil that is thicker than that, in colder weather your engine may not get the lubrication it needs. FYI, engine oil numbers indicate the viscosity of the oil, (the weight, or heaviness of the oil.) Higher numbers indicate thicker oil, and thicker oil may help if your engine is burning oil, but it also takes longer for the cold oil to get into the bearing surfaces.

No cheapest supermarket 20/50 is more than ample unless you intend to take on the best at LE MANS or the INDY 500

Questions, no problems. 2002 Chevrolet Malibu, 72,500 mileage. 1. Pros and cons of switching from regular oil to a synthetic (AMSOIL). Also which oil is better for the car during our heat wave of 100...

if you have the 3.1 liter engine than don't waste your money on synthetic. There are several known mechanical issues with that motor that synthetic will not help with. It will last just as long on conventional oil.

If you live in a part of the world that sees snow than synthetic will help with cold weather start ups.

If you have any oil leaks synthetic could make the leak worse or it could make it better.

Synthetic is of course more expensive. It does not mean you can run longer intervals between oil changes. If the engine is tight and efficient and extended service interval with synthetic oil is a possibility. If the engine has higher miles, starting to show signs of wear and is no longer as efficient or tight as it once was than extended services are not an option and may do more harm than good.

Interstate batteries are one of the best. Exide and NAPA brands would be the next on my list. Stay away from brands like energizer, werker, batteries plus.

I’m happy to assist further over the phone at

Does the 2005 chevy malibu use synthetic oil

Hi, you should use energy conserving oil from Mobil One or ELF synthetic that comes from a container stating, "designed for use in GM vehicles". You will save money on gas, on oil changes, sludge will NOT form inside the engine, and everything will last longer.

What type of oil do i need fot cts 2003

Regular 5W30 oil will work just fine in the '03 CTS. Your owners manual will tell you to stay away from any other viscosity (5W20, 10W30, etc) because they will be either too thick or too thin. It does not require synthetic as it is equipped with a 3.2 liter engine that was more or less derived from the Catera, but just didn't break as much. They only ran that engine for a year and started using the 3.6 liter VVT (variable valve timing) which does require synthetic oil (5W30 Mobil 1).
