PICK UP A 5GALLON PALE OF SAE 30 ROYAL PURPLE HIGH PERFORMANCE OIL ANY ONE HAVE ANY ISSUES USING THIS IN A SBC BRAKET ENGINE

What is the part number on the container?

I've run the XPR 5W30 for quite a while in a 900+ HP N/A - SBC. Rumors of it changing for the worse with the Calumet buyout as mentioned. Not true based on the samples I had tested in 2019.

I've been in the RP facility several times and it isn't rebranded Valvoline.

I was also involved in some sliding wear/cold scuff testing on the RP diesel oil years ago. the RP performed better than all of the other HD diesel oils tested.

If I were to switch to another oil based on analysis, it would be High Performance Lubricants (former RP personnel) or Redline.

The RP info is deteriorating in here fast! I think several different brands use the same blends in their products. There's a big difference between re-branding and using the same blend right?

I'm not sure where re-branding entered this discussion? I do know the Valvoline syn is 40-50% less money. Anyone into saving money using R P should do the research as to if it is the same blend, I don't use it, but I have been told it is the same, by a couple people who would know.

I don't know where the OP went but I'll pose my original question on the topic.

Was the engine assembled using plastigage, or was the engine assembled using a dial bore gauge?

My opinion on topic is, there's a slight chance 30 wt oil is the correct oil for the engine year round, if a dial bore gauge was used.

You are the one who said Royal Purple is Valvoline with dye added. You want to know how that got into this discussion look at your own post in this very thread.

Lots of lab test data on both but not the SAE 30 mentioned

Paul, what specific oil did you run?

I used the Schaeffer’s 40W Micron Moly. #110 Race oil
I’d buy 5x 5 gal pales at a time for $420 to my door.
I see Amazon sells it, but I’d have to review a lab test sheet to be sure the additive package is what I ran.
It should have
200 moly
1750 P
1800 Zn
1650 Ca
I ran straight weight because it lacks a multi viscosity additive that makes any oil sheer out of grade in hard use. The base stock was 100% paraffin, which is ideal for methanol fuel. Some terrific engineering went into that oil.

Paul how do you manage the bucket as far as measuring etc? Use a bucket pump?

On mine, i use the 5 Qt dispense can. Has a flexible neck and a thumb tab open /close. Spring loaded. Similar to this. It's an old Plews unit.
about 25 years old and works just fine.

I poured it into clean empty plastic milk jugs. Costco ones are durable and have a real screw on lid. That was bulk, for oil changes in my shop. In the trailer, I just kept refilling old Schaffer 1 qt plastic containers. At one time I bought it in a box of 12 qts they also sell.

I use the safe oil setup as paul, and use these jugs to measure and pour.
