Alright who here runs 20W-50 ( or higher )
- Thread starter FCD
- Start date
- Status
I used a lot of this in my old air-cooled single cylinder motorcycles
Penrite HPR 20W-60 (called HPR 30), its a mineral oil that API SM, ACEA A3/B3 and VW 502 00 / 505 00.
SA = 1.29%
Calcium = 3150 ppm
Zinc = 1570 ppm
TBN = 9.7
KV100 = 24.2 cSt
KV40 = 229 cSt
It worked well in the Audi and Kingswood too.

Here's a 14 year old thread...

(It's why I call B$ on 8% between 0W20 and 0W40 BTW).

Yeah, swayed by the purple prose. I was going to get HPR30 for it next, but there was a sale at Supercheap, and the V Twin was down to just very expensive, cheaper than Edge, so went for that. Made myself feel a bit better by getting a lone bottle of Silkolene 2 stroke semi at half the price of Penrite semi on sale. Looking forward to a smell test on that.

I've seen Castrol 10w-60 on shelves here, and 20w-50 of course, but not the 25w-50 you showed. If I recall correctly, the 20w-50 is simply an SN oil, with nothing else to it. The 10w-60 is that BMW thing, I believe.

Yeah
I've never had the pleasure of using it, I hear it's very close to a monograde and so shear stable. It should work very well in a air cooled motorcycle. I was going through a big Penrite HPR 30 stage when I had the right vehicles to run it, now that I see how good it is, it's just too much oil for what I own now.

Yes we get the Edge 10W-60 synthetic too, it's more aimed at the high performance modern Euro car people. I've used a ton of it in my water cooled, 4 valve head motorcycles, that produce high revs (> 10,000 RPM).
The Edge 25W-50 is a mineral oil aimed at the old school pushrod V8's with 2 valve heads. It should work well in air cooled motorcycles with low revs and two valve heads.

I'd gladly try some of that Edge 25W-50 or Penrite 20W-60 if i could get it cheap, i can't get it cheap however so... Valvoline VR1 it is for me, although now that my Capri has stopped burning oil i am considering trying a 15W-40 HDEO or M1 5W-50.
Has anybody done or seen an UOA on Pennzoil 3623 25W-50 GT Performance Racing Motor Oil?
Searched here in UOA, but cannot find. Did find this reference, however:

I mostly used it for top offs in boats and OPE. I was born in the 80s so by the time I started wrenching the change to thinner oils started
Here is a recent 2017 UOA of Castrol GTX 20W50 after a 3000 mile run in a Nissan 300ZX

It looks very good with only 1ppm of Iron wear metal.
The add package looks nice too with 57 ppm Moly, 108 ppm Boron and 1094 ppm Zinc. So no problems with the modern GTX 20W50 being reduced zinc, it has ample.
For detergents Ca is about 2000 ppm and Mg about 100 ppm.
Looks like a good modern thick oil to me.

No shear at all on my UOA, so pushed the next lot of 25W-50 to a longer oil change.

I have seen UOAs of GTX from about 2 years ago and seeing it had only 600ppm of ZDDP, if this is true they have raised it.

That's the question, is the GTX 20W50 they buy in the USA the same as the GTX you buy in Europe or the GTX I buy in Australia ? I know we all get different Magnatecs.
Then, the second question is do they change the formula at some stage. To be honest, that is why I prefer oils like Penrite HPR 30, as they clearly say on their data sheets what the zinc level is and the update the data sheet with a formula change. Same with your Valvoline VR-1, you know it's a high zinc oil

I stopped using GTX 20W-50 when it went SN...didn't trust it after that.
I could get GTX 15W-50 locally for really cheap, if it had over 1000ppm of zddp i would use it with no doubt.

Is your Edge UOA posted here and do you have a link ?

Last time I used 20w-50 was ten years ago when I used it for my summer run in my 4 cylinder Ford Escort Station wagon and was committed to that regimen since I moved to KC in 1988 for my 4 cylinder vehicles and distance driving.
Oddly enough I am again considering in potentially purchasing 50wt oil with a moly/boron additive to mix with my 30wt oil stash as an option for my 2 warmer weather runs. It appears the 40wt oil I am currently using has slowed consumption markedly to an acceptable number approximately 1/3rd qt burn rate for 2800 miles of driving. So it looks like my valve seals is the culprit of the oil consumption issue in my vehicle.

I just noticed these two Penrite oils on sale at my local store
Penrite HPR-15, Full Synthetic 15W-60 (API SN, ACEA A3/B4)
TBN = 10.2, SA = 1.21%, Zinc = 1080 ppm
KV100 = 23.9 cSt, KV40 = 175 cSt
Penrite Vantage 20W-50 Mineral (API SN)
TBN = 7.6, SA = 0.83%, Zinc = 1080 ppm
KV100 = 17.5 cSt, KV40 = 152 cSt
Thick and full 'o zinc
