As many of you know, the ACDelco UPF64R is the recommended service filter for the LE2. The PF64 is not recommended not is any of its cross references due to issues with many of them having the PF48 bypass specification, not even the newer, higher, PF64 bypass spec. Many companies finally...

I had my DEF tank heater replaced under some special warranty at 44,500 miles maybe around Oct 2017, dealer topped off DEF when they performed replacement. Now I am at 58,500 and have driven 14,000 miles, my DEF % just hit 35% left, if I do a little math and ran to empty it would be 21,500 miles...

New Type Regen!! No fuel usage when throttle is lifted. Today I witnessed a new type of Regen. I started using massive amounts of fuel 12.00 -13.00 Liters/100kms. I lifted the throttle to make sure it was a regen no fuel usage, I did this several times, it never showed fuel usage during lifted...

Is the fueling system E85 compatible? I know there isn't a flexfuel sensor and that the car is not tuned for E85, my question is if E85 is used will it damage the fuel lines, seal, etc.?

Some dealers, including MINE, do NOT use the TPMS Re-Learn Tool to tell the DIC the location of the tires after tire rotation. Note your air pressure PRIOR to rotation, better yet, ask them if they use the Re-Learn Tool to reset the TPMS tire locations. I checked the price of this tool...

I did a little post-analysis of the Volt data from Volt stats! last night. Here is what I saw based on gas usage. It shows what percent of real-world drivers are able to achieve certain levels of gas usage, and it's pretty significant. GM could easily cut the range of a plug-in Cruze in half...

All my vehicles drop mpg in the winter, Smokey Yunick was a big fan of using exhaust heat back into the engine. Also, almost all cars, including the 88 up TBI GM V-8 Engines used a thermostatically controlled Hot Air duct from the exhaust manifold. I'm gonna try to duct some hot air into my...

Reason I ask is because when trying to program in a cell phone, that gal locked up in my radio kept on mentioning OnStar. My dealer assured me, using this feature has nothing to do with OnStar and strictly between my cell phone company and me for usage charges. Owners manual states to contact...
