Oil limitations

I just got some new oil for the WK to put in this weekend but am not sure if it meets the specs. Can anyone tell me if they have tried Castrol Edge in their 5.7 HEMI and how well it worked out. I have been using Royal Purple for a while and that has worked very good but thought I would try something different. Now I wish I would have stuck with what I know.

honestly, as long as you used the correct oil weight, you shouldn't have much of an issue.

There are specs called out on the bottle but not the jeep spec. That is why I am inquiring.

Anyone else use edge in their 5.7?

If it's not listed on the bottle then it more than likely doesn't met specs.

^+1.......if you cannot verify the oil meets the 5.7L OEM specs then you'd be well advised to get another type.

Or they didn't pay to have it "meet the specs" most any name brand oil will far exceed manufacture oil recommendations.

But for the sake of this thread and to help you sleep at night only put oil that states it meets the specifications in your vehicle.

I think that would help me sleep better. I did the oil change last night with the Castrol Edge so I will just wait and see. Probably do a quick turnover on it. I did find online a cut sheet from castrol that says that it does meet the spec.

The other issue is the oil light and P0520 that I got earlier in the week. Same symptoms as indicated in the post that is linked.

What is it about the Castrol that makes you leery of it meeting specs for an 11 year old Jeep? Royal Purple certainly isn't a magic potion for WK HEMIs that nothing can stand up to. It's expensive motor oil - nothing more, nothing less. Assuming a regularly maintained service interval, most any oil out there with the proper weight is gonna work fine for your vehicle - to include parts store house brands.

I have been driving vehicles of various types for around 50 years now. I try to buy the cheapest oil I can that meets the manufacturers recommendations. That usually turns out to be store brand oil.
I have NEVER had an oil related break down.
The high priced oil meets it too but I can't see paying extra money for the name.

On a side note: How many of you believe this commercial for oil that has "intelligent" molecules?

The only reason that I even thought of the specs is after utilizing the cheap coolant I found myself in need of replacing the radiator because of leaks. Not saying that it was the cause but I did flush the whole system and got the better stuff.

In the Hemi I'd use a good synthetic because of the fact that 5w/20 is required and using syn makes it less likely to have oil viscosity breakdown issues. The 5w/20 is very thin....

Aww come on, where did you see that or what brand? I really can't believe any company would say that in a commercial. If it's true it would have to be in the running for the stupidest hook ever.

The MDS system doesn't like anything heavier.

I had Royal Purple my last 3 oil changes. I only buy it when it's on sale. I haven't found it on sale for ever so I just went to costco and got the castrol edge for like half the cost.
It's full synthetic and it's 5-20 I don't really understand what your concern is with using it. I don't even understand why, being on sale, made me buy Royal Purple.
