I haven't been on here very long but I know enough to take JB's posts about GM with a grain of salt. My 3 vehicles (car, truck, and boat) do have GM engines in them but I'm fairly open-minded when it comes to vehicle brands. None of the GM vehicles we have owned have ever had oil consumption issues. The original catalytic converter on my truck lasted 220,000 miles and 12 years.......
JB bashes GM in about every post and makes out like Toyota's are made out of magical materials and super close tolerances. Neither claim is really true. It's like reading an automag where the writer secretly has stock in Toyota lol.
GM engines don't particularly use much oil. The problem with some cat failures was more of a quality control issue and a mechanical faailure and not really anything to do with oil and additive. The EPA wants the additive out of the oil too. Sure the CPFI was problematic after higher miles and the low quality gas deserves part of the blame, but it's not like Toyotas and Hondas didn't have problematic distributors, timing belts that had a limited life, rusty exhausts, transmission failures, squeaking brakes, sludge issues etc. What CARB does isn't necessarily a fair endictment on an automaker. Oh well.
