Good story , but it's still an advert by Rotella.com
Well I can tell you a story I know is true because I was the one doing the driving & service but on a smaller scale. The wife & I owned a mid 80's Oldsmobile Cutless Ciera w/a V6 Diesel(a true diesel not a gas converted mtr). I had bought it from my parents they told me it would use a quart per tank of fuel & on an average the car would get about 35mpg using any diesel fuel so I figured I could live w/using a qt of oil w/that mileage.
On day I was talking to a buddy who was an over the road truck driver & told him how much oil my car was using. He asked me what type of oil & fuel I was using & I told him whatever oil is used for diesels & fuel from where ever I could find it. Well he told to at least use Rotella Oil & try to use Shell Diesel Fuel because of how clean it was & that they always put the winter additives in it.
Using just the Rotella Oil my oil consummation went from one qt every tank of fuel to one quart every 3-4,000 miles when I would change the oil. Plus when I ran Shell Fuel & Oil my MGP went from around 35mpg to about 45mpg and in the winter I never had to plug the car in even when it got below zero here in Illinois.
And that folks are the TRUE FACTS of my use of Rotella Oil....Joe
