Hurricane oil pressure

[go-ram]

Thunner oil would be a 20 vs 30 weight. Not 0w. Vs 5w. The fact Amsoil is saying a 0w-30 is "thinner" than a 5w-30 just reaffirms my dislike of Amsoil. And shows they are more concerned with marketing than truth.

.
That's not what the Amsoil article said, methinks you didn't read it carefully:
"It’s helpful to think of the “W” as standing for “winter.” The lower the oil’s “W” viscosity, the more readily it will flow when cold. In this case, 5W-30 will flow more easily at startup than 10W-30."
.
Both numbers are viscosity ratings, one at low temp, other at high temp.
.
You use your favorite oil, I'll use mine, let's just leave it at that. But perhaps this excerpt from Castrol's website will help you understand more clearly that both numbers represent resistance to flow, they are both viscosity values:

https://www.castrol.com/en_us/united-states/home/learn/car-maintenance/oil-viscosity-explained.html

"Viscosity is the resistance to flow of a fluid. Motor oil viscosity grades are based on a scale developed by the API (American Petroleum Institute) lubricant organization. The values are defined in a specification known as API 1509 and are based on the resistance the oil gives to flowing at two different temperatures – cold and high temperature. The measurement of viscosity at high and low temperatures are properties of multi-grade oils. Years ago, most vehicles used one viscosity grade oil in the summer and a different viscosity grade oil in the winter. But as motor oil technology advanced, additives such as viscosity index improvers allowed for the use of the same grade of oil year-round.

The low temperature viscosity of the oil is a measurement that simulates starting a car on a cold winter day. That value has the letter “W” after the number and has a dash after the W. For example, if the oil is a 5W-30, the 5W part describes the viscosity of the oil at low temperatures. The lower the number, the faster the oil will flow at vehicle start up.

The high temperature viscosity is the number after the dash and is related to the viscosity of the oil as it is moving around your engine after the car has warmed up and is at normal engine temperature. In the 5W-30 example, the 30 defines the viscosity of the oil at normal engine temperatures. Again, the lower the number, the lower the viscosity of the oil and the faster the oil will move around the engine."

I don't need a lesson in motor oils. But typical Amsoil user/distributor thinks they need to educate people.

I don't have a Hurricane, but I myself would never run a 0-weight oil in any ICE that I owned. And whatever weight oil I ended up using for a given ICE vehicle, I'd only ever buy it from Amsoil. Email tech support at Amsoil and get their opinion, can't hurt and likely will help.

Just curious why you wouldn't run a 0w weight oil? Not being confrontational, I'm just curious. Why wouldn't you want your oil to flow better when cold?

Interesting, since the 3.6 in my 21 Wrangler calls for 0W-20 and I've run that for close to 90K now with no issue. What is the logic behind the blanket statement?

It's called ignorance about oils. And still thinking it's the 70s and 80s

I've been running 5W-30 in my previous 5.7L and current 3.0L SO.
The 2.0L in my JL Rubicon calls for 5W-30.
I think 0W-20 is about gas mileage not engine protection also 0W-30 would be a great option too.

The Supercharged Hellcats are Running 0/40.... I don't think it's about MPG....lol.

It's called for 0/40 in the Hellcats too... Been running it since it was new in 2021 0/40 PUP oil, no issues whatsoever.

I'm about to change the oil for the first time in my 2025 Rebel 3.0 SO. Just hot 6k miles.
I saw it specified 0-20 and figured I'd move away from that given that I'm in the Arizona desert.
The dealer parts guy did say 0-40 was recommend but I wasn't sure if he was just confusing the HO spec or actually recommending it in the SO as well.
I came to the forum to see if it was common to move away from the water thin OEM recommendation. As I've done also with my Ford EcoBoost engines.
I'm now considering 5w30, which is what I already use in our other vehicles.

New guy with a 4 day old truck w/3.0.
The oil pressure was bit of a shock to me being low by my experience with my old P/u 7.3 diesel

Guess I'll see how the 3.0 holds up.
