Greetings all.
recently purchased a 2009 g6 with the 2.4. 43,000 miles This car is rated for 43 mpg Canadian . I figure I`d be happy with 38 to 40. This thing is lucky to see 30 mpg . Not impressed. I have a `03 Buick Century with 140,000 miles that gets better mileage and it still has original plugs . rant over .
The air filter on g6 is fairly clean . I was told fuel filter is in the fuel tank !! . has anyone swapped out the original plugs in these 4 bangers. What else can I do to get mileage up . Tires are up and no mil light showing . Or is the best these cars do !
Thanks Muff
