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.
You can include protein sources, which contain saturated fat, in an acid reflux diet by reducing the associated fat. For example, while whole milk and whole-milk products may contribute to acid reflux, skim milk or low-fat yogurt may not be as problematic. Other low-fat or fat-free dairy products, as well as lean meats with all visible fat trimmed off and poultry without skin, are other proteins you may include in an acid reflux diet.
