Royal Purple users?

Time to change the oil on my blazer (91) and pickup (84) for the winter. I normally run 10w30 summer and 5w30 winter. Last few oil changes were with Mobil delvac (spelling?) and a quart of lucas break in / high zinc supplement.
I know oil choices can get real personal but I'm wondering what you guys think of giving Royal Purple a try?

I am no scientologist but it is exceptional imo. I would use it in any extreme duty application but a tbi350 to me isnt one of those applications.

Be careful with full synthetic in a sbc... That stuff nearly leaks right out of the bottle imagine what it would do in a small block... Just kiddin it's good stuff I have it in 10w30 for when my 383 is broke in finally

Yep, good stuff, redline oil is good too

Sounds like someone needs to discover the BITOG forums.

Be warned: it’s an addiction and you will be on there for hours your first few visits. Hours. Trust me.

I just had to Google that, but once it comes up, I remember how much time I've spent there when researching my oil questions.

i love royal purple (in a platonic way). i have used it in a TBI car with great results.

Does your 91 have roller lifters?

 

[TommyD11730]

Doubtful, it's a GM crate motor.

I used Royal Purple break-in oil when I first started my new small block 350. After that I started using Valvoline VR1 Racing oil.

I use it in my fleet of vehicles.

The reason why i ask, is because, in my case, I THOUGHT i needed a thicker weight, so i used 20W-50 AND ALSO because the engine that i used it in has flat lifters----- and 20W-50 royal purple had the high zddp requirement. Not sure if the other royal purple viscosities have sufficient zddp?

At 100k I swapped all the lubes in my Dodge dually 4x4 to Royal purple... gearbox, transfer case, axles...stayed with Rotella for the Cummins...the 6 speed shifted so much smoother, and I noticed the truck coasted a lot further when I pushed in the clutch...

I'm just about at 200k now and I will be changing all lubes with Royal purple again..
