    Redline MPG incr vs Volatility of Gasoline

    Back around the beginning of March, 2004 I switched from Pennzoil 5W-30 to Redline 10W-30 and immediately noticed a 7.1% MPG increase. The car also seemed peppier. I kept wondering if the increase was because of the oil or because the refineries switched to a more summer blend gasoline. I...

    Red Line Oil and MPG increase

    Auto RX in transmission

    I am currently cleaning my transmission with Auto RX. The directions say to put in 6oz, drive 1,000 mi, completely change the fluid, and you're done. Yet for the motor application the directions are to drive 1,500 mi then rinse for 2,000-3,000 mi with a non synthetic oil and you're done. Does...

    Change Oil After Storage? Yes Or No

    I only change the oil and filter on my motorcycle every fall. It sits in storage from November thru March. I can't see that it makes any difference if the oil sits all winter in the bottle or in the motorcycle's oil tank. I have never had any trouble and get good UOA's. I use synthetic, but I...

    ATF Mazda 626 2001 2.0L 29,487mi

    These cars are notorious for tranny problems. The transmission seems to be working fine, but this analysis is horrible. The ATF is the original OEM factory fill, which I believe is Mercon. I will be changing the fluid quickly. I would appreciate any comments and/or sympathy regarding this...

    The Post Office threw out my oil sample

    First post! After learning a lot on this board I decided to do a UOA on my car. I ordered two kits from M. Sparks - great service too. I took the sample and threw it in the mailbox - mistake. Two days later I get a "Contents found loose in the mail" msg from the PO. They returned the data sheet...
