    I always run straight 30 weight oil with high zinc in the older injuns... what do ya'll run? I've heard Lucas is good... and Deep Purple (wait a minute that may be the name of a rock band scratchchin image ) ...something Purple anyway suppose to be a good motor oil. In fact, I heard that Purple would pay for an engine if it expired and you could document that the Purple stuff was used since the engine was built? (that won't do me any good but makes me think they must think an aweful lot of their oil) smile image

    Waiting on your suggestions... gents and gals... the reason I ask is for the Little Red TA since it has quite a lot of miles on it and I want to drive it again but also want the best protection while running along with 1tinindian and RockSho and Sarge and PonchoFreek and the rest of the "Breakfast Club" down the boulevard ! yes image

    Shaker--

    You're showing your age, my friend. The oil would be Royal Purple, not Deep Purple (although the hue is quite deep). wink image

    I use to run Quaker State or Castrol 30W but switched to Shell Rotella diesel at the recommendation of my mechanic (in response to comments from Jim Sawruk while he was still alive) based on the flat tappets and their requirement for zinc in order to stay properly lubricated.

    According to what I've been told, Shell reduced the level of zinc in Rotella in 2009 in order to conform to tighter emission restrictions.

    I've heard there are additives which help, but I am also in the hunt for a replacement oil. I guess it's either that or get a motor from Butler with a full roller cam! biggrin image

    I'm a believer in CASTROL. THe Blend seems to work great in all my GM cars. It's easy on the pocket book. I was always told after a rebuild or new motor stick to the oil you start with. Has'nt failed me in my 40 years driving.

    Thanks for the memory jog Tinman... flamed image

    I used to run Rotella 30W for the reason's you pointed out... same thing-recommendation from engine builder. Now that Rotella has changed some things I am using The Chevron Diesel oil but I understand the zinc has been dropped in it as well. I'm OK in Blue with roller tipped rockers but would sure like to find a better oil for Red. Perhaps the "high mileage" Castrol would suffice.

    Is anyone using the Lucas or Royal Purple?

    10-4. I'll run Lucas in the rear end then cause the Little Red TA does knock just a bit once turning off the interstate... she does ok if you service her with GM additive for awhile then after a few months... well anyway Thanks Shain. I may call Royal Purple to run in my engine.

    BTW - what a name for a motor oil - somebody must have been taking crack and hilucinating when they named that oil perhaps listening to DEEP PURPLE Tinman- lmao image

    But I wanna do something for the old sweetheart (Little Red TA)!

    As we say in the trucking industry... "Closing Dispatch". biggrin image

    Ya...no complaints. Lon Moyer is very good friend of mine who built my motor. He has done a few motors for me in the past. He was big in the NHRA scene and most recently working with Hendricks Motor Sports. I absolutley trust him.

    I use Castrol High Mileage in the '77, it has an additive that causes the seals to swell and helps stop some of the leaks. There is an additive called ZDDPlus that replaces the zinc in motor oil for those flat tappets.
