Using AMSOIL in a GM vehicle calling for dexos1 is 100% safe even if it does not appear on their little list of certified oils that you must pay GM to be on. Re: Oil Filter Location on the 5.3L Oct 23 2011, 12:18pm
Re: does peanut butter affect acid reflux. I'd say yes! Peanut butter is probably one of the most-acid inducing foods because it is primarily fat. It requires more energy to digest (just like any other fatty food), which requires more acid to do the job. Lay off the PB, and switch to a low-fat carb-based diet.
People who suffer from both peanut allergies and acid reflux may not realize at first that their peanut allergy symptoms are showing up in the form of a bad case of acid reflux. Keeping a journal of foods that you eat will help you see the pattern that acid reflux symptoms worsen when you eat peanuts.
