Just curious why you went from Mobil 1 ESP 0w30 to this. Longer drain interval?I believe 10.4

I’m not the one to ask for why certain manufacturers blend the way they do. I can say I’ve had great results with AMSOIL Signature Series 5w30 as well as HPL PCMO 5W-30 and they’re both in the 3.1-3.2 range.Forgive me, I’m new to learning about the technical properties of oil but an HTHS of 3.11 on the AMSOIL Signature Series 5w30 seems very unimpressive when Liqui Moly and many euro spec oils are >3.5. Is there any reason for this?
I still use Mobil 1 ESP 0W-30 in 6 other vehicles I own and/or maintain. My Jeep is my toy that get abused so I went with one of the best. Not that Mobil 1 ESP isn’t amazing.Just curious why you went from Mobil 1 ESP 0w30 to this. Longer drain interval?
I figured you would've stuck with a euro oil with a higher HTHS, especially for something that gets a little abused. Just inquiring, no judgement from me.I still use Mobil 1 ESP 0W-30 in 6 other vehicles I own and/or maintain. My Jeep is my toy that get abused so I went with one of the best.

I’ll only end up doing around 10k per year with the Jeep. I really like getting under it to inspect for damage. I know I won’t be able to handle going over 6 monthsVery nice! What OCI are you planning on with the SS?
Absolutely! If you drive gently then you don’t need as high of an HTHS. Good example is my gently driven Civic, it’ll be fine with a 0w-30 oil that has an HTHS number of around 2.6 to 2.7. For my Corvette, which sees full throttle blasts often and higher oil temperatures, I’m more confident using a Euro 30 grade with a 3.5 HTHS number.Makes sense, thank you. If you have a lead foot, is a higher starting HTHS more important?
Only in SAE J300. When you see an oil manufacturer's spec sheet, the KV100 and HTHS viscosity are exactly those values at the defined test temperature of 100C for KV100 and 150C and 1M/s shear rate for HTHS viscosity.Like viscosity, HTHS is a range.
A xW-30 should have a higher HTHS viscosity than that. Typically should be over 3.0 ... the minimum HTHS in SAE J300 is 2.9 for a 30 grade. Minimum for a 20 grade is 2.6. HTHS of 2.6-2.7 is more like typical xW-20 territory.Good example is my gently driven Civic, it’ll be fine with a 0w-30 oil that has an HTHS number of around 2.6 to 2.7.

Exactly"Going under to check the shock absorbers...hmmm...is that a plug in the oil pan?"
I made a typo, I meant to type 0w-20 for my Civic. I’ve only ever used a 20 grade in that car.A xW-30 should have a higher HTHS viscosity than that. Typically should be over 3.0 ... the minimum HTHS in SAE J300 is 2.9 for a 30 grade. Minimum for a 20 grade is 2.6. HTHS of 2.6-2.7 is more like typical xW-20 territory.
