So today I changed the oil and use 1 quart of
Marvel Mystery Oil (MMO) and 4.4 qts of 10W30. I also added 6oz to 15 gallons of gas. I will attempt to add 4oz per 10 gallons of gas until the next oil change and log the results.
Here is the last log entry prior to adding MMO:
6/12/08 231.3 miles, 15.807 gallons (87) 14.63 MPG - this tank did include some trailer towing, several loads from Lowes, and some 4x4 driving.
MMO Added to oil and Gas:
Initial reaction, truck is definitly more peppy and has slighlty differant tone. This is a surprise, I did not expect to notice any immediate change.
