Penn vs Valvoline test results..Ed Wright
 
Earlier I started a thread that morphed into oil comparisons. I had been using Brad Penn 10-30 and tried some VR1 straight 30 with test results for both. Ed asked for me to post results back then so here's where I am so far. Here's the original thread http://classracer.com/classforum/sho...ght=ron+gusack.

Testing is from Blackstone. I put 9 runs on fresh 10-30 BP with a new Wix filter and 12 runs with fresh VR1 straight 30 and a fresh filter. I sent both samples in at the same time to eliminate Blackstone's machine calibration from being a factor although I don't know if different test machines were used. I divided the number of runs into the amounts of aluminum and iron for each oil to compare wear. I don't really know what I'm doing but I think I'm learning stuff so if you see major flaws, please jump in.

Brad Penn 10/30
9 runs
aluminum was 12/9=1.33
iron was 36/9=4.0
zinc 1652
phosphorus 1482
molybdenum 1
viscosity at 210F was 56.6 and should be 62-74. This could be because I had 3.8% fuel in the oil. Less than 2% is their acceptable range.

VR1 30 weight
12 runs
aluminum 9/12=.75
iron 20/12=1.66
zinc 1351
phosphorus 1271
molybdenum 58
viscosity was 59.7 at 210F and should be 62-74. This could be because I had 3% fuel in the oil, which I gotta figure out. Less than 2% is their acceptable range.

Judging from these results, I'd say the VR1 is a better oil. I don't like all the moly in it and it's the main reason I got away from VR1 back in the 80's. Tear downs always had a bunch of black slime in the pan and I hated it. A Valvoline tech told me it was moly. It was sorta like the paraffin we used to find in Quaker State engines in the 70's. Blackstone's tech told me that up to 20% of old oil remains in an engine when a change is done so the VR1 has some BP in it. I'm gonna go back with VR1 30 when the season starts and see what the results are and I'm going to up the number of runs between changes.

Great info thanks for the post, the results are a little surprising to me . What oil and how many runs was on it before you added the Brad Penn , just asking if 20% of earlier oil may have had an effect on the results.? just wondering...

The engine has only had BP 10-30 since it was built, which was 146 runs before the 9 test runs. The VR1 went in at 155 total runs so it will start the year at 167 runs. Blackstone said "up to 20%" I doubt that I have anywhere near that cause I let it drip until it pretty much stops and that's with the front end up. I'm sure there's a fair amount trapped in various places, but 20% seems high.

That 20% might be a little low for Brad Penn. That oil is gooey and is stuck to everything. I usually run BP in all my motors, so at the tear down it is very messy. For better testing results you should have used an engine flush. Your results would have additional weight in making a very good determination.

I told Blackstone that I was going to stay with VR1 for at least 2 more changes to have a better chance of having all Valvoline by the 3rd or 4th oil change. I told them my plan was to do AAA-BBB-AAA testing instead of A-B-A.

How many runs are you going to do between changes? What do others do? Thanks.

Thank you!! So far I have stayed with VR1. I use 10W30.

Always use VR1 10-30 on both cars! (Engine builder direction).

I don't change it often. I cut the filter open after each race. Guess it gets a new quart in the new filter each race. New oil about mid season. Clean oil, clean filters, I don't see the point of more often changes. May be why I don't see a pan full of crap like some discribe.
