HDEO in a jeep

[k2xj]

Hello everyone,
Im new to the board...would like to say that this is one of the best forums i have been on for information.

I have a 95 jeep cherokee. I have read alot about using some of the HDEO (15w40 or something like it) in a jeep. Are there any concerns about using HDEO in a gasoline engine over a long peroid of time? Is anyone exclusively on HDEO in their jeep and for how long?

Your insight is appriciated.

For starters...

Living up north I would be concerned using a 15W40 during the winter months. However I've been using Amsoil 5W30 HDEO in my 2000 Wrangler with no problems. I've had it in about 7-8K miles now.

I use Delo 400 15W40 in my wife's Jeep GC. It comes in four gallon jugs and the Jeep takes six to fill with filter change. In the summer I put all 15W40 but in the winter use four quarts 15W40 with two quarts Chevron Supreme 10W30. This is our 4th Jeep with the 4 Liter motor and it now has 145,000 miles on it with no motor problems as all the previous ones.

Assuming the HDEO you use is also rated for gas engines, why would you expect any problem?

You mean liters, right?

Jeep 4.0's like the XW40 oils. In your climate the Rotella T 0W40/5W40 would be a good choice. Amsoil 10W40 might be another good one to look at.

Don't forget Valvoline Premium Blue Extreme 5w-40....

My Jeep likes 10W30 just fine:

This was Chevron High Mileage @ about $2/quart.

Last year I did run a mix of Delo 15W40 and Chevron 10W30, because I picked up some Delo by mistake.

I have been using Delvac 5W-40 in the summer months (mid-June till mid-Sept.) and Esso XD-3 0W-40 (both are HDEO) the rest of the year for around two years now on my 01 TJ and my 99 XJ....both with the 4.0L and they run great.
