Shell Rotella T5 Diesel Oil - OK In Gasoline Engine?

[4wd]

It foams like a beer. It's also quite volatile and skimpy on the add pack with no Mo and low B. I personally wouldn't use it in anything I care about. Some people are fine with "good enough" and look past it failing D892. I'm not one of those people.

Yeah, remember when everyone said that’s what to put in 4 stroke outboards - I posted where a senior mechanic ran that and his OEM oil in twin motors at WOT - guess which got the foamy dipstick …
Of course that just launched attacks on NMMA …
(Who does test for foaming and corrosion) …
These were $23k each motors

I've been using diesel oils on and off in my cars with gas engines for years with no problems at all.

Yeah. I ran the stuff in my wife's 2008 v6 Hyundai sonata during the summer after it racked up about 150,000 and it ran till 270,000 miles after she sold/gave it to her idiot friend who never changed the oil.

It’s my understanding that T5 and T6 have not changed formulations since they carried the gasser approvals ~5 years ago or whenever it was.

I wouldn't want to go as thick as 15w40 in an engine with the factory viscosity ratings those have, but they are durable mills and I used the T5 10/30 in our 2003 Town & Country for quite a while before selling @ 235K miles.

I've run 10w30 T5 in my 4.0 Dodge Nitro 14 years, when I can find it. It use to carry a SM rating, but they removed it. Currently at 242k miles on the car.

I would save it for the summer and run a 20% ratio of MMO with the HDEO. On my older Corolla's, I do this every year or two. I typically run this for a full 5k OCI.

If this HDEO foams, you’d think Ford/Navistar and CAT would put out a bulletin advising not to use it to prevent damage to a HPOP or HEUI injector on certain engines.

Prolly depends on engine.
When I got 1997 VW (brand new, back in '97) with 2.0 engine it came with 2 years maintenance included and dealer used 15w40 oil, so did I after free maintenance was over, and for at least next 10 years. Later played with xw-40 and xw-30 oils. Had the car for 17 years.

I've been running 5w40 T6 for about 20 years in everything I've owned. Probably 25-30 vehicles in that span.

It’s a v6 dodge. The engine most likely dates back to the ‘60. I use it in that kind of engine.

 

[MrWideTires]

I used T5 10w30 in a 2005 Subaru Legacy from 30k miles to 250k miles.

Never had an issue with the car, zero breakdowns, changed the oil every 8000 miles and it burned maybe half a quart.
It got passed down to my little sister and then sold for cheap after like a year with 270k. No idea what happened to it after.

Update: I did use the oil. I did the spring oil change in late April, and changed it out about a week ago (early September) with almost 10,000 km (about 6000 miles) on it. Over half of that was highway miles.

The van drove fine, and there didn't seem to be a measurable fuel consumption penalty.

The used oil appeared to be quite thick coming out. Perhaps, as a semi-synthetic, it didn't hold up as well as a Full Synthetic would have.

Back to my SuperTech 5W-30 synthetic.

Would I do it again? With this very durable low-tech pushrod engine, sure, but in summer only.
