Brad Penn was bought out by D-A Lubricants a couple of years ago and they have re-named the product line PennGrade 1.  I've been using it (15W40) for probably the last 10 or 12 years in the Shelbys and our Porsche 993's.

I'm a little surprised at the number of people using 20-50. Why is that preferred over something like 10-30?

Thanks,
Steve

Well I am no scientist but the formula is rather simple, The hotter the engine gets from usage the oil gets thinner. So therefore we need thicker viscosity oils to fill the void between bearing surfaces. Regular street engines would and could run safely on ANY modern type oil, basically any brand and any viscosity. Where things get a little tricky is if you are breaking in a new engine or you are running a solid cam application. Solid cams need ZDDP in the oil so we don't wipe out the cam lobes, again I'm no metallurgist but trust me it happens to a few that don't use ZDDP and are just putzing around. I use hydraulic roller cams in some of my cars and the usual break in period with the usual break in oils are not necessary. So there are just a few things to consider here, solid cams,breaking in an engine,what oil pressure, and rpms the motor will experience. These few items will guide you to what oil you feel safe with. With a standard hydraulic 302-428 low rpm cruiser type cars. get whats on sale at your local auto parts store,these engines used regular 30 weight 50 years ago and lasted thru the years so don't be afraid of ANY multi viscosity oils for your rides.

Most speed shops carry it, you might try in your area. Otherwise Amazon and eBay sell it and some sellers offer free shipping.

   "Green oil" , whatever name is on the bottle , Kendall , Brad Penn , Penn Grade , DA  whatever. For the race engines I change it when it turns color . The late Harvey Crane got me using the stuff almost 50 years ago.  "If it's green , it's working , if it's not , take it out". was his words to me. Daily driver , hydraulic roller engines get 5-30 synthetic. Race car hauler gets 20-50 VR1 because you can get it anywhere on the road . Different needs , different oils.

Great day for an oil change. Went with 6 quarts of Valvoline full synthetic 10W30. Aviad oil pan incidentally and 5.0 roller rocker modern engine made to look period correct.
