In the Bosch IF/IR alternator world, most regulators are of the A-circuit type, meaning they are regulating on the negative side of the rotor coil. Is there any disadvantage to changing to a B-circuit type regulator designed for the same alternator family?

Aside from not being the most optimal choice in many or most VW diesel applications, certain VW Long Life 2 oils continue to look like reasonable PAO-based "high ZDDP" ACEA A5 options for gasoline engines. Is there anybody having negative first hand experiences in terms of increased oil...

Thank you 2EHA - I do not think so either.

While some OEMs are moving “back” to silicate or phosphate containing coolants, some OEMs never moved away from incorporating inorganic inhibitors into their specifications or preferred coolants. Overall, it seems that the advantages of inorganic inhibitors outweighs their disadvantages as long...

Some of these Bosch "1-wire" IF alternators with "multi function regulators" (MFR) have got a dedicated tach or "W" connector sticking out from the rectifier plate. Most however do not. I am wondering if there is a way of adding one without too much hacking and soldering. If you look at the...

Sounds good, thank you!

Does anybody know how a Cummins 3.9 or 5.9 OEM oil cooler is being held together and what materials are involved? Are the plates and oil passages made of copper or brass, and are they brazed or merely just soldered together with something like 70/30 solder? I would like to know as I am...

Have your lawyer contact them! What kind of punishment are they facing for making such "mistake"? I think these guys and others are getting away with it because nobody cares and major companies like BP/Castrol, Mobil, Shell etc. don't bother because they have left the vollsynthetisches motor...

Thanks, it is very interesting for me to hear about that type of business. Your 6B definitely does some work if you are burning like 6 gal./hour. Please keep us updated.

You've got enough data to see a trend towards higher soot levels. Could it be time for new injector nozzles? Overall, everything looks more or less consistent and probably not too bad for a truck that actually does some work. To get an idea of how hard this engine is run, what is the rated HP...

Thanks for sharing this report. I do not understand how a lot of serious stuff gets so little attention on this forum. Interesting how "much" Fe was carried over from the previous OCI. Aside from the Cu leaching issue (or non-issue), this report looks much better and cleaner than others you have...
