TPain Posted March 7, 2012 Share Posted March 7, 2012 What's the lowest weight I can go in my 85 GL-10? Lookin' to maximize fuel economy. Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted March 7, 2012 Share Posted March 7, 2012 Heh. You should not go any lower than recommended in your manual - which is 10w30. Going lower may help you mileage very slightly - at a much higher cost in engine wear. If you want economy then sell the turbo and get one with an NA engine. Turbos don't respond well to attempt at super high economy. They need to run rich to prevent detonation and bring down exhaust temps. Poor mileage is a hallmark of owning a turbo and it something you learn to live with..... Or blow up engines. GD Quote Link to comment Share on other sites More sharing options...
TPain Posted March 8, 2012 Author Share Posted March 8, 2012 Thanks General. I'm getting about 25mpg I believe. Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted March 8, 2012 Share Posted March 8, 2012 That's very good for a turbo automatic. I get a solid 16.5 mpg in my '91 2.2 turbo SS. And it only drinks premium. GD Quote Link to comment Share on other sites More sharing options...
