I've been running Rotella T6 5W-40 in the Jeep since I bought it. Manual recommends 10w30, but the engine seems perfectly happy with a 40 in it. Startup thickness doesn't seem to be an issue, it cranks at normal speed, fires right up, builds pressure immediately and sounds fine down to 0* F (haven't started it in anything colder).
Anyone here use HDEO oil in gas engine?

I have used straight HDEO's in my Jeep with good success, mostly Rotella, but I do tend to blend it a lot. Even though the Jeep specs 10w30 the Rotella is probably thicker than necessary. I have blended the dino Rotella with PYB 5w30 and the results were very positive. In the future I'll be blending Rotella with QSGB instead, I realized after some time the add pack in QSGB is more similar to Rotella than PYB so it may create a more consistent blend, but I've not actually tried it yet to compare results.

I`ve read that HDEO`s (well,at least some) have a "soot control" additive. What exactly is that?
I have a Toyota 4Runner "06" V6 that I ran Shell Rotella I think the oil was a 5-40 a few summers ago and it ran just fine in my truck this was around the 40,000 mile mark. I now have 130,000 on the truck and it runs great but I don't run the Rotella anymore the only negitive I found was the truck seemed slugish running it. I just stick with a good synthetic now 5-30 or 10-30.
I have been running Rotella T6 5w40 in my 93 Chevy 1500 with 305 v8. I have been running it over a year, and it is the best oil I have tried in it. It was sludged pretty bad, the T6 is cleaning it, and the noisy lifter has quieted down. Oil pressure is good, and cold starts have been smooth.
I used to use rotella 5W40 when towing more than manual allowed in Subaru. Got good UOA. Took a MPG hit in short trip driving.

Keeps combustion by-products like soot in suspension so the engine doesn't get gunked up.

"Lubrizol advanced dispersant systems keep carbon soot particles separated in suspension, thus limiting abrasive wear. Lubrizol detergents and anti-wear chemistry control wear and deposits in both in the modern and heritage engines."

Would soot control be a consideration for the newer DI engines? Asking because there have been lots of reports that the 3.5L ecoboost is creating soot in peoples tailpipes. Just curious if tailpipe soot could mean there is crankcase soot also.
I use T5 10w30 in our current Explorer. I used it in our previous Explorer as well. I know a lot of local guys that use T5 in gasoline engines. Seems to work very well for everyone.
I've used Chevron Delo 400 15w40 in old Chevrolet and Studebaker V8's for nearly 30 years with good results. The engines stay clean inside and I'm seeing low wear rates as the Studebakers very rarely need their valves adjusted. As long as the oil has an S rating and not just a C rating, it will be fine for a gas engine.
Using Motorcraft SuperDuty 10W30 HDEO in an '05 F-150 5.4L V8. When those stocks are used up, it will run on RT T-5 10W30 HDEO. The only HDEO you should run in a gasser is one that is dual API rated. Most of the new mixed fleet oils are CJ-4/SM. As 46Harry said, as long as you have both the "S" for spark ignition and "C" for compression ignition, you can run the oils in either venue.
I've go Petro-Canada Duron Synthetic 0w30 in the G5. Probably won't be an on going thing though.

The oil additives address soot build-up on the lubrication side of the engine. IIRC, most of the DI gas engine build-up is on the intake passages/valve where there is no oil contact (other than the residue that the PCV intoduced into the intake) or gasoline wash from conventional FI to clean the intake valve area.
Here's a good read...

I have no issues with running hdeo in my stuff. I worked for uhaul in 1997 and they used 15w40 in everything. Probly a smart move considering the lack of maintenance many trucks there had.
I don't see a problem running HDEOs in a gasoline engine....but you really gotta look at the specs.....make sure the diesel oil is API rated.....for one.....secondly, you want to use something that is "close" to your recommended oil weight....
I.E....Don't go running 5W-40 Diesel oil in a newer model Ford
Definitely would not work! Those engines have "tighter clearances" and you'll likely incur damage on cold starts (or so that's what the manufacturers want us to think....as they are specing lighter weight oils now....).
But yea, a good 15w40 HDEO, during the hot summer months can't hurt
Just change it out before the first cold front of winter......and yea, I've also heard of people "diluting" them down with say, MMO, etc...to thin down the weight a bit....not a bad idea really......MMO is, last I read, equivalent to a 10weight oil.... so it may knock it down a grade or so Then again, lets keep this thread to strictly HDEOs

Yeah, I have used HDEO with great success in a motorcycle which is of course gas powered.
Now on to a bigger question. I see many HDEO extended interval drains in some diesel pickup tricks in the UOA section. That said, why wouldn't someone be able to do a pretty extended interval with just a gas car and HDEO? I am very tempted to try this out, but I would not bother with a UAO since my cars are pretty old and I don't care much right now. If they were to die, I am just about at the point to buy new anyway. Any input on doing an extended interval on HDEO?

I'm on my 3rd OCI of Rotella T6 in my WRX, and I'm looking to my fourth by March of this year.
What I have noticed is that it seems to look cleaner longer than regular 5w30 synthetics, and also that my consumption has dropped from 1 quart/2000miles to practically zero.
HDEO's are wonderful for turbocharged engines IMHO.
