CK4 spec oils.

Interesting stuff. It is crazy to watch the ever evolving world of motor oil. Lets just hope oil that works well for HEUI stays around. These engines are a little more oil picky than others.

I'll hopefully be calling you later this week for a pail of 8700. Going to run that for 5k and then probably switch to LE 5-40. Just want to get all the junk cleaned out on the 15-40 before going to the more expensive stuff.

no sense in going to 8854 in a 7.3 if you are going with 8700... maybe a couple oci in winter but that's it.. 15w40 will hold icp better.

More worried for winter. Should be able to get one extended oci for the winter on it though.

I wouldn't try to extend it in the winter unless you do oil analysis.. old motors dilute oil..

I plan on doing one around 5k. Driving a lot of highway these days so they'll go on quick. However with that is going to come more idle time to warm up.

I switched to LE about 3 months ago. I went with the 5w-40. You say the 15w40 holds icp better? Maybe I'll go with the LE 15w40 next time see if it makes a difference.

It will hold ICP better at wot. I usually recommend it first. If I didn't in your case I apologize. I'm usually pretty annoying about explaining all that stuff. But, you may give up cold start smoothness. Depending on your climate. So it's a balance.

I was just going to steal it from your sig. lol. But thanks. Hopefully later this week I'll be giving you a call

So the 15w40 has better cold idle characteristics?

The other way around, in heui engines. The 5-40 cold starts better, but you give up ICP hot. 8800 15-40 is a good happy medium as its cold start characteristics are better than most 15-40s but hold ICP petter than any 5-40. All 5-40s are a little lower viscosity at operating temp than 15-40. It's just the nature of how they get those oils to do that spread. And all 15-40s are higher vis at lower temps.
Basically this is just important in heui, in non heui the difference is really only important in very cold temps like below-20 and in very high power applications.

yeah what he said^^^ I should have explained it that way. but I think Billy was just being a smartass.. lol

No worries Pal. I'm just trying different oil's at this time to see if I see any difference's. I have an oscillating idle at OPT, but cold it idles great. I'm sure it's due to some tuning issue's. I like synthetics as well, they seem to do the best in my trucks. I usually run 5w-40 from Schaeffers, but thought I'd give LE a try. Out here in CA I could run a 40w year round and not have any issues. I've actually thought about it, I just haven't tried it yet.
