I own a late 2006/ 2007 Chevy Malibu. I purchased 10W-30 oil from the auto store and when I got home and went to check the oil, I noticed on the Oil Cap, it says 5W-30. The engine is a 6 cyl and it has auto-start. Also, I'm due for an oil change in about another 2000 miles (which probably doesnt matter). Will it be okay to use this type of oil? Will it have any effect on the gas mileage? Or will is 10W-30 oil better? Please help!!

I would put the required type of oil in the car, esp. since it is new. If your oil change isnt for another 2000 miles, then you shouldnt have burned that much oil. I have a 2007 Malibu SS and it takes 10w-30. W=weight and I know on the LT, LT2, and VE models, the engine is either a 4cyl or v6, meaning that the engine is needing oil that is a lighter weight.

Only time 10w oil will be a problem is in minus 30 degree weather. And if you have some milage on the car like 50/ 60 thousand I would be using 10w/40w oil any way for the extra clearences worn engines have. There is a thermometer and oil Viscosity chart in the owners manual that will back up what I stated above.

No it will not have any effect at all, the first number is for winter.... the W stands for winter, so when it gets cold out the 10W-30 oil you put in you car thins out to a 10 weight oil, which is thinner and better in the cold so it can flow through your engine. The lower the number the thinner the oil.

it's ok if u put one quart, actually this year i'am using 10w40 cause expecting not that much cold thi year, especially on my 2000 cavalier that the fan is not working at all so i 'am using 10w40 but i always warm up the car first . 10w40 cool the car faster then 5w.
i'am wondering what did u add a quart of oiil in it , do u have any leak around the engine or is it buring oil ?if it's burining oil thru the muffler , then yea u have to use 10w .i'll suggestthatu sell it if the oil is burning or if it's thru a pan gasket, or cover gasket, then change the gasket or keep it that way . good luck

Not at all. The 5W-30 would be slightly better for very cold weather. Just wait till your next oil change.

Use 10W-30 in the winter and 10W-40 in the summer

Using the recommended viscosity on new low mileage vehicles is important because it is essential to the ability of the oil to adequately flow into tight bearing clearances and carry the bearing load but those bearing clearances have substantially loosened with mileage on your 1991 Caprice and I am sure that 10W40 will flow just fine and do no harm.

No it will not make a difference. if you live in Canada then it will. in Canada it will start to become cold so a 5W-30 oil is great because of cold starting and is a lot easier on the engine to turn over. if you live a warmer place, like LA, then you don't have to worry about it.

Use the recommended oil 5-30W newer cars/trucks have more smaller moving parts you need a thinner oil to work threw thous parts to lubricate them properly .

I've got a 2004 Pontiac that is the same way. I've always had it serviced at the Pontiac dealership and they have always put 10w30 in it. So I guess it's fine.
