: If in doubt...ask the rodders around you what they use.

: The lifters, 215 or LR are made for 20-50.

: The only secret to this engine's longevity is frequent oil changes.
: 2500-3000 miles. It also has a low pressure high volume oiling system.

: Synthetics, wonderful as they are, are made for high pressure and long duration.
: In other words, if you are treating this engine correctly, they are a waste of money in this instance.

: Use a mineral oil with decent detergent properties and that is all there is to it.
: Those with older blocks should consider the Castrol for high mileage engines.

: The main problem with using oil too long is "Coagulated Pentane Insoluble" or more commonly known as SOOT, that black carbon crap from incomplete burning of organic compounds, that turns the oil black.
: Oil will suspend it until it reaches the saturation point, at which time it becomes a liquid abrasive wearing everything, especially those soft bearings!

: So synthetic oil will only last up until the saturation point, just like regular oil, but it's under HIGH TEMPERATURES, Synthetic oil survives where Dino juice fails!

: Some think it will last forever and end up slowly ruining their engine, polishing it's bearings away.

: The only place you need to use Synthetic, is under extremely HARSH temp's and pressures conditions, where only it will survive, but it still should be changed regularly.
