I bought one awhile back but ended up never installing it. I changed my mind and figured it's best to let the plastic cap be the sacrificial piece should something ever go awry, not the threads on the engine-side filter housing. Plus the correct torque spec will not be the same for aluminum vs...

Once the water temperature gauge needle has moved any noticeable amount from minimum stop, which would correspond to somewhere in the ballpark of 125°F water temperature. Turning it on sooner means I'm just blowing cold air onto myself while slightly prolonging the warm-up time.

A Davco 382 in a pickup truck..... man that would have been a sight to see 😁

Air brake systems can tolerate a modest amount of leakage. Air is the working fluid, and there's an unlimited supply of it. This is not the case with hydraulic brakes, which use closed hydraulic circuits containing a finite volume of fluid. Even a small fluid leak can render the brakes...

Electric heater for de-waxing on initial startup, with return fuel heat to keep it warm and flowing once it's running. They still manufacture many of the OEM fuel filter / water separators for heavy duty trucks to this day.

Not only that, but it protects horsepower too !

It does for Class 1 and 2a. Only in the realm of >8500 lb GVWR does it not apply. With that in mind, the targets are lower for light trucks, hence one reason why it is advantageous for automakers to crank out so many different models of ugly front-wheel-drive station wagons and call them...

CAFE. That alone might be enough to kill it.

It's all about generalizations, and assuming all other factors are kept constant. Of course, that's seldom if ever a valid assumption.

Some smart chargers also have the capability to "test-discharge" the batteries at a specified current to estimate their remaining capacity. If there's an extended stretch (many months) where the batteries aren't actually used or deeply discharged, it might be a good idea to use that to "refresh"...

2 micron is very fine filtration, overkill even for many modern common-rail diesels. Of course that's not a problem in and of itself, but consider pressure drop especially as the filter gets loaded up and restricted. That could be quite frequent especially if you're looking for a more compact...

I'd go with a 15W40, especially if it's the HEUI 7.3L in your sig.

In general, OCIs for heavy trucks are less dependent on mileage, and more so on engine hours or fuel consumed. This is especially true for severe-service tractors and trucks, which (unlike line-haul tractors) tend to operate over a wider variety of vehicle speeds and variable load conditions...

Having read the spec myself, I can confirm it does not conflict with SAE J300. In other words, they are in fact minimum values, not ranges.
