Buying whichever brand was on sale at a discount was his advice. Ken didn't have a preferred oil brand to recommend. For many years I was using Havoline 10w-30 in my daily driver 455, with a coupon I was paying $0.39 a quart for it. The inside of the engine always looked clean and I never had any oiling related issues.

Personally I've used numerous different brands of oil including diesel oils and all were more than satisfactory.

x 10 - my dad once worked with Shell oil. With the huge array of different colored oil containers on store shelves, it's easy to forget that there are limited sources of oil and refineries, yet an astonishing long list of oil brand names. Unsurprisingly, if you select any oil based on viscousity and additives and blindly compared the brand names, you'd find them to be nearly identical because most are. Insider's secret is that most oil is sourced and blended with additives before being sold to oil distributors. The pricing differences are primarily costs for marketing, distribution, and pretty packaging on final consumer product. I've seen the inside of enough engines to know it is abuse and/or neglect that kills engines, not the brand of oil. Select based on viscousity and additives needed for your particular application and you'll be fine.
