Swimmer, GM back in the early 80's decided that 5W30 was a cost saver verses different oil wts for different areas of the contentntal US and Europe. So, in cold weather use 5W30 and in warmer climates use 10W40. In Cinci. Oh. I switch between the 2

I jsut bought a new car and am about to do my first oil change at 1000 miles. I also always thought that you were supposed to wait longer to do the first oil change to let the piston rings break in, but almost everyone that I have talked to says this is not the case. The dealer also told me something about the engine being broken in at the factory, but my car is a Mazdaspeed so yours may be different. Anyway the system says 50% oil life left because it works based on mileage. It will hit 0% when you have gone the reccomended miles for a change. The station will reset the system each oil change and it will start counting down again. The 3,000 mile 3 month rule is BS and was coined by Jiffy Lube or other places like that to get more business. Look in your owners manual for the true reccomendation. Most cars say 5,000 to 7500 miles for normal driving. If you take frequent short trips or drive your car very hard you should change it more often. If it were me I would find a G5 forum online and see what other people say for the first change. If you don't want to do that I would just change it now and then change it at 5,000 miles or so from now on.

Answer 4

It depends on where you are, and how you drive. Check your owners manual.

I would go with 5W30 for most situations. Always use the same brand and grade of oil, change the oil and filter regularily 5000 miles is okay under most situations, but at least twice per year.

The only people I know that have had engine problems due to oil were those that tried different kinds of oil. Pick one and stick with it.

Answer 5

Always look at the owners hand book. Your car came factory filled with 5wt / 30wt energy saving motor oil always replace the oil filter too AC delco filter reccomended. Down here in Texas I like to use 10wt / 40wt. There is a themp chart to oil Viscosity in the owners book.

10w-30 is what the General motors dealers use
