Re: 0W40?
The ONLY reason 0w oil was created was to reduce emissions and increase fuel economy, primarily during a vehicles warm up period. Anyone who says anything else is drinking the corporate kool-aid...

Re: Prototype Piston Award Signatures?
At Lycoming, for our air cooled aircraft engines, the pistons aren't machined round, they are ovals and they taper from top to bottom. That way when they expand at operating temperature they are...

Re: Service parts identification sticker
That is total bullsh*t. He's reproducing a sticker. Not only that, there are multiple VIN stampings on the car that identify the vehicle. The sticker just identifies trim. While someone could get...

Re: NOT MINE! In Atlanta Georgia Fixer-upper
Yeah, not worth anywhere near 15k in that condition. Seller should take 9k and run far away. 15k will buy you a slightly rough condition but drivable car with the same mileage.

Re: which gas
Ethanol based 91? Or 91 octane with ethanol? "88 Octane" is E15. So I'm guessing you mean regular 91, but with ethanol. Typically 10% or less. That is the best choice, with replaced injectors. ...
