[QUOTE="Johnny O, post: 941601, member: 61743"] Using synthetic is between you and your wallet. Some oils ARE better than others as far as holding viscosity over time and wear metals parts per million (ppm). Getting a used oil analysis (UOA) is the only way to know for sure. I belong to a site where people get UOA's and post the results in different engines. I can save you $25 a few times over and tell you that Motorcraft oil is hands down the best stuff for the money. Pennzoil and Havoline are also very good for conventional oil. I got good UOA's with Mobil 1 but better UOA's with Pennzoil Platinum which costs a buck less a quart. Use 5w-30. It is what the engine is designed for. Grandpappy may have used straight 30 weight in the Farmall for 30 years but it isn't the same thing. Modern engines have tighter tolerances and are designed to be run with thinner oil. The manual says to change the oil and filter every 5000 miles. [/QUOTE]
