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.
Despite being calorie-dense and high in fat, peanut butter may actually help you control your weight. Peanut butter is a source of protein, vitamin E, B vitamins, potassium, magnesium, zinc, manganese and copper -- making it a healthy addition to your diet.
