    Gone to the Dark Side with Supertech

    Just did an oil change on my Camaro, and had to take stock of where it is in its life-cycle. I have owned the car since new, and it always had synthetic oil in the sump. But after 240,000 miles, oil consumption has trended up, and now it is using a quart in about 1200 miles. This gets kind of...

    2008 Dodge Ram 3500, 13k miles, MCSD 15w40

    2008 Ram 3500 diesel: batteries going dead

    I have been having a problem over the last few months that if the truck sits for 2-3 days, the batteries will go dead. It doesn't happen every time that I let it sit for a couple of days, but it's happened a few times, about 2 times a month. And sometimes even if it has just sat overnight, it...

    Installing oil temp gauge

    I am installing an oil temperature gauge in my 2008 Dodge Ram diesel and want to use the 1/8-NPT port on the top of the oil filter base. Has anyone used this port for this purpose before? Is there any issue with the sensor blocking off an oil passage? The sensor I bought can be trimmed for...

    Gave in to temptation.

    I've been saying for a while that Kendall Super D-XA is an oil I want to try, but the only place I could find it was at Pilot truck stops, where it was overpriced. But for the last couple of weeks, I have been seeing it in various Pilots around the country at $13.99 per gallon. So I finally...

    Which fluid for G56?

    Once again, the age-old quandary of what lube to put in the G56 6-speed manual trans in the Dodge Ram diesel. I have been running AMSoil ATF, which is what they recommend for the application. Chrysler recommends their C+4 ATF fluid. In my opinion, Chrysler really screwed the pooch by...

    2008 Dodge Ram 3500 - Turbo screech

    Over the last couple of weeks, I have noticed a screeching noise every time I engage the exhaust brake function. This truck has a variable-geometry turbo that closes down the VG mechanism after a couple of seconds' trailing throttle. This assists decel of the truck when towing or heavily...

    2008 Dodge Ram 3500, first sample

    I bought this truck in Missouri, and put about 1000 miles on it before doing the first oil change. I don't know the miles or type of oil in this drain interval, but will be doing more oil samples to settle on a change interval. This truck has EGR and DPF emissions controls, so I was worried...

    Time for a change - 2008 Ram 3500

    The last few months of towing with my 2001 Ram 2500 had been getting progressively more difficult. The operational pattern had fallen into MAKE A RUN, FIX THE TRUCK, MAKE A RUN, FIX THE TRUCK. It had run reliably through July, but started giving trouble in a big way when the injection pump had...

    Rainbow's end.

    If there's a pot of gold at the end of every rainbow, do you suppose there was one at each end of this one? Sadly, I didn't get a chance to find out: it was gone five minutes after I took the picture.
