0w or 5w-30 with HTHS of 3.5 HTHS or higher

[GI_GRIFF]

I have been studying 0w and 5w-30 oils a little that have a 3.5 or higher HTHS value. So far, I had this reply back from Castrol USA. I sent the same request to Mobil and Pennzoil/Shell, I am waiting for replies from those two yet. Some that I already know of are Kendall GT-1 Max Euro 5w-30 with 3.6 HTHS and a couple Liqui Moly products, their 5w-30 Top Tec 4600 and their Top Tec 4210 0w-30 both which are >3.5 HTHS. Motul has 8100 X-Clean+EFE 0w-30 with a HTHS of 3.5. Anyhow, I will post what I got from Castrol customer service.

I've used all 3

Of those three, what did you like the best? I have used the Royal Purple HPS and loved it, but I didn't realize until now it had an HTHS of >3-5.

No best as I was happy with all 3. I use Royal Purple HPS 5w30 in our riding mower still to this day.

You know, HPL and Amsoil are probably the best money can buy. I am just not willing to pay the initial cost. Thanks for the info TiGeo.

Is Pennzoil Platinum Euro L 5w30 still available? It has a HTHS of 3.5. Local Walmart always had it.

I don't know.

Or M1 ESP 5W30?

 

[GI_GRIFF]

M1 ESP 5W30?

They still sell this at my local Walmart here in Nebraska.

My local Walmart has none of this in stock, but you can order it online from them and have it delivered to your door. I wonder if Walmart is phasing it out.

It's still on the Pennzoil website. But it also still shows it as Dexos 2, which ended in 2024.

What's your application? HTHS > 3.5 seems like a must for air cooled OPE but it's been quite a while since any mainstream automobile needed anything like that.

For some reason I always thought it was more expensive than SS. TIL.

I never understood why, even despite the higher HTHS, AMSOIL says SS is their top of the line oil, over Euro.

Edit: the LS is more expensive. What's the difference between LS and MS? SAPS level?
