Great choice for your older Vehicle.
Style: High Mileage 150K, Size: 5 qt (Pack of 1), Configuration: 5W-30
Trusted and put to use many times with my 2006 Pontiac G6. I have over 140,000 miles on her and she is still reliable and running great.
I love the fact that it also helps clean away the built up grime etc. in the Engine
