what oil should I use pennzoil platium 10w-30or pennzoil high milage 10w-30? I never heard of the pennzoil platium. my neon has 116,500 miles on it and its a 96 highliner. I know the regular pennzoil 10w-30 won't stay full. I added pennzoil high milage 10w-30 and stays at full level reading on dipstick.

 

Pennzoil Platinum is fully synthetic, so unless you want to pay the extra money, I'd stick with the high milage stuff. Especially if you have any oil leaks right now.

 

the platium oil is 50 cents cheaper than the high mileage oil

 

Really??? Even though, I'd stick with what is working for you.
