First you said you use 0W-20 in your Jeep for warranty. Then you said you use 0W-20 in your Jeep because of the short trips.
Name two reasons why your Jeep needs a heavier oil.
Have you done an oil analysis to see the harm the 0W-20 is causing in your Jeep? No.
Why do you need choices in your Jeep if you will continue to use 0W-20 for warranty purposes?
Why continue to use 0W-20 (even under waaranty) if you know a heavier oil is better for you? That was asked of you and you remained silent. I don't expect a response either; at least a civil one.

Reality is, for the way most people drive, these new low viscosity oils are a good thing. If you're tracking the car and driving 150mph that changes things......
+1 And unfortunate imo to read at least one poster commenting who in the past went so far as to pm a study showing the benefits of use of thinner oil now questioning Ford's desert testing of 5w20 as shown in
this document.
And as said, if one doesn't like not having a choice of oils because of warranty concerns then one should buy a vehicle where oil choice is possible, simple. But, seeing as many seem to think they know more than the engineers and munufacturers who tested the engines using xx w20 oils, using thicker oil under warranty shouldn't be a concern. But I've had no engine problems running 5w20 since 01 in what is considered the south so I've found no reason to go thicker than recommended.
A long time ago someone posted(paraphrase) that while cafe 'may' have been the motivation for thinner oil use, the resulting xxw20 oils have proven up to the task and much more. That's how I see it.
As an aside I'll have to say that the level of civility 'by some' commenting here is sad. That said, considering one of the posters commenting here using derogatory labels such as 'fan boys', at least no one has been called a traitor yet for using the recommended xxw20 oil. While I do find the level very surprising by some, in that case it's absolutely no surprise at all.
In the end though, glad to be able read the thoughtful posts like the one above and by Caterham and some others.
Do you have a list of new American vehicles that offer oil choices? I wouldn't buy a car based on oil choices, so if that comment was directed at me I just want to clear that up. I will however go on the record as trying to avoid direct injection as long as possible. lol
And for the record, people can change their mind, if their research leads them in another direction can't they? Or once a decision is made you must take it to the grave with you? Happy Thanksgiving!
