Went to change the oil in the wife's oil burning Equinox 2.4 since the OLM went off, although I changed it about 3000 miles ago with plain old Pennzoil yellow bottle after a BG EPR treatment. The BG EPR did cut way down on the consumption, thankfully. Was surprised that what I thought was Pennzoil yellow bottle conventional now says "Full Synthetic". Curiously, it does not mention Dexos. So, even though I didn't spend the extra $ to get Platinum with the Dexos approval, is it plausible this "Full Synthetic" is probably OK for the 4-5,000 mile intervals that the OLM seems to favor?
