This is not advisable. You should use 10w 30w in this vehicle. Unless the 10w40 has been advised by the manufacturer.
the best fuel would be 91 octane or premieum.
what tools do i use to change the front brakes in my 2003 Pontiac grand prix
No, I would not recommend using synthetic in an engine this old. Use a good 10w40 conventional oil.
As long as the engine is ok you can use: 10W30 10W40 I recommend using Vavoline.
Thank you for the answer

Yes, but you may have wiring issues. Usually, it's not worth the hassle. Use the correct tranny.

Should u use 10w30 or 10w40 in the winter
The 1994 Pontiac Grand Prix can use any SAE certified coolant. In normal climates, the coolant can be mixed half-and-half with water.
