I'm not going into a full post about Penray's many products. They have a web site, http://www.penray.com/ for more information or you can request catalogs through them or Cummins. They are the official supplier to Cummins Engines.
For an idea of some of their products, see the Lubro-Molly post. Penray makes equivelants of most of those products.
A product I have switched to is their MAX POW-R PLUS Cold Weather Diesel Fuel Treatment. This effectively replaces the LM Cetane improver and anti-gels in one can. It also adds lubriciity, FI cleaners and water dispersants. Since a can treats 125 gallons instead of LM's 25 gallons, and the price is about half to boot, you can see it's attraction in my diesel vehicles.
Diesels also call for an anti-fungi & bacteria product. I know, sounds crazy, but diesel can actually support and become contaminated with bacteria and fungi that will clog up the system. An old and excellent product for that was called Diesel Doctor, which came in a tube and a tube full would treat a typical auto tank. It was dropped once, but I see recent ads indicating in may be back in production. Again, a product I put in the tank before a fuel filter change.
However Penray makes another, Fuel-Prep 1000. It has an amazing side effect, it becomes a fuel preservative.
Fuel-Prep 1000 is again concentrated for the big rigs so a pint treats 125 gallons. Even the big tank on my Cummins Dodge truck gets just a few ounces. But the good news is that the anti-bacteria agents don't hurt gasoline, so it can be used in gas cars as a fuel preservative or stabilizer. Penray suggests a double-size dose when used as a gas storage stabilizer. Works great in my generators, chain-saws, antique cars, and perhaps your Westy if it isn't driven regularly. An excellent replacement for the grossly overpriced Stabil at the hardware store!
Caution: Penray supplies the big truck market; even gas engine products are still geared to that end. So you will often find their quantities and concentrations more suited to that market than home use. Also, they provide many specialty chemicals for big rigs & diesels which ARE NOT suitable for automotive use. So don't just rush in and buy something because it's cheaper -- be sure it's intended for YOUR use in your aluminum VW engine! And then measure quantites per directions.
