I meant ditching SP add pack for more detergents. To your point on the mix I had read elsewhere with such an “experiment” in mixing VR1 viscosity and a 50/50 mix came out too thin for a real 15w40. To that end that’s why I went 2qt 10w30 to 4qt 20w50. I doubt still that it’s perfect but I’m...

Disagree in that apparently Valvoline using an otherwise SP add pack that lowers calcium helps Zinc’s effectiveness. I’m citing a Motor Oil Geek video as my source though he cites SAE/API as the basis for the change to SP and IIRC shows snapshots of their white papers which is good enough for...

Dexjs. He doesn’t do work for the public (I’d asked) but he does do a core return service putting new pistons on core connecting rods. It’s the only reason I actually went through with my DIY in frame rebuild. However it seems lately he is running into sourcing issues for rod cores and is...

Later Jeep 4.0’s have issues with cracked piston skirts causing this noise caused by pinging owing to overheating. With that wear shown you should drop the oil pan to see if there’s pieces of skirt in there. Mine didn’t so I went another 10k before rebuilding but all 6 pistons were in fact...

*Edit* Disregard; missed that it being GL4 vs. GL5 was the issue.

Never had an issue with seals using synthetic ATF in an older vehicle. My more recent experience has shown the extra spend for something like Redline or Amsoil is worth it over conventional if its a vehicle you plan to keep "forever". I'm keen on Redline D4 or High-Temp depending on...

Does anything push you ever so slightly toward one or the other? Funny enough, I can't find anywhere to actually BUY the HPL; it's listed on their site but not for sale on their distributor's site.

No, I do believe you're correct.

Have the same question for an NP242 chain drive. Consensus across the internet was that cheap ATF would "mist" out of the breather and was not ideal and that New Process/Venture specified 5w30 motor oil. Doesn't seem like the ideal fluid either. My searches through the forums seemed to...

Thing is, Redline IMO is not "subpar" and I thus have yet to make a switch though I can see HPL being marginally "better". I also don't need a quick answer. Part of my curiosity is whether I'm the only one with this concern. If I am, I'll just stay with Redline. At the same time, I wonder...

They seem to be active on the forum, so I don't see the explicit need for it to be direct. It's also not like its defamatory or anything, and I'd also like to hear from others on the subject. I'm sure HPL would too. Fully converting to a "blue" fluid is a good number of spill and fills to...

My go to ester/PAO ATF has always been Redline D4, but I would also be into trying HPL's ATF Blue CC. With shipping and BITOG15, its a wash for me money wise but I like how active and cutting edge HPL seems to be with R&D & customer service. However, I'm not really into the idea of an ATF...
