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.
Eating low-fat or fat-free cottage cheese is good for neutralizing acid reflux symptoms. Cheese such as feta, goat and soy cheese are healthful options. Fat-free cream cheese and fat-free sour cream allow you to enjoy food without the heartburn.
