Question

What type of oil should I use in my 2002 Pontiac Grand Am?

Thanks!

Answer 1

The best thing to do is use the same oil every time. You can make a change to what you want from the old owner. 10w 30 is a good basic oil. You can also use synthtic if you like just keep using the same kind.

Answer 2

I'm glad you asked, as this does not come up often, surprisingly.

The car calls for 5 W 30 and I recommend 10 W 30, unless you're operating in constant blow freezing conditions.  Viscosity just isn't there on 5 W 30, and my oil life monitors constantly confirm that, GM Onstar diagnosis will tell you too, if you have it (since 2006), as I do on brand new G6 GT same as Rolex Grand am GT racer.

I use Valvoline and mostly Castrol GTX hi-performance oils, same price as all.  Used to buy 20 W 50 in pre-unleaded fuel days, with softer engine parts, but now 10 W 30 as I said, but..........  oil alone is not good enough!

Use either Wynn's Xtend additive or the best Lucas Oil Stabilizer.

My cars last forever, and recently, another engineer told me that I could keep my driving oil in twice as long, "for the environment", so 10,000 km. or 6,000 miles, and none of my engines use or dirty the oil.
