Be careful you don't break that egg between your foot and the gas
pedal. :~)

Nyuck, nyuck.

One might can squeeze an additional mpg out of that new truck by going
with synthetic lubricants though I do recommend a thorough break-in with
conventional mineral oil. I did two each 4,000 mile stints when my '01
PowerStroke was new; 4,000 with the factory oil and 4,000 with Castrol (or
somesuch). At 8,000 I moved it to Amsoil 15w40 HD Diesel/Marine. I put
about 30k a year on it, the biggest majority being highway miles between
Houston and the San Antonio area. Most always getting 16.5 - 16.75 mpg.
Me thinks the switch was too soon. Suddenly, around 160k my fuel mileage
jumped a whole mpg. Me thinks I may actually have retarded break-in and
that the engine has just now loosened up. I'm pushing 164k now.
Whatever, I'm not complaining.
And, I have an eight foot bed behind a four-door crew cab. Gawd it's a
long truck.

I am considering using a snthetic for the first time in this truck. The new
vehicle engines use such light viscosity oils these days I want maximum
protection against oil break down. I really do not drive this vehicle too
much and oil changes are usually 1 to 2 times a year at 3,000 mile
intervals. I wonder how a synthetic would do compaired to regular oil in
holding up for 6 months at a time with few miles.
