Hello and does anyone here use a HDEO like Rotella, Chevron Delo, and others in a gasoline truck or car? Curious as my neighbor down the road from me has a 94' I think Toyota Truck 2wd and he is using Rotella T5 10W30 in it, has like 329k on it. He goes to 6,000 miles then changes it with a purolator classic. I dont think I would run a HDEO oil in a modern fuel injected engine cause I think it might be a tad heavier than whats called for in the owners manual. Thanks in advance.
 
I`ve read that HDEO`s have abrasives in them that can be harmful and cause wear in gasoline engines. Is this true,or a myth?
 
Any HDEO rated for the same API spec as your car requires won't cause a problem.

I run Rotella T5 0w30 in my Dodge Stratus right now and it works fine. Its HDEO, but the oil itself also meets the API SL specification for gasoline engines.

If it meets those API specifications for gasoline engines...its fine. Alot of people would argue they're better, since the oils also go through a battery of diesel-specific tests and usually contain more ZDDP antiwear additives.

I'm not sure what to say. Myth.

Maybe you confused HDEO's with straight Diesel oils?

As stated, pretty much no problem. My Volvo has been on HDEO's for most of it's 150K miles.
 
Pablo, I mean diesel oils that are like the Rotella T6 5w40, syn blend 10w30 and Conventional Rotella 10w30 etc. Talked to a guy I know that has a bunch of older cat dozers(uses them to help his strip mining job) and he said that he heard Rotella and other diesel oils have additives in them that help hold grit, debris and gunk in suspension a lil' better. True, maybe maybe not.

No technically those are not "diesel oils". Those are mixed fleet HDEO (Heavy Duty Engine Oils). They will work fine in most any gasoline engine.

True diesel oils are completely different animals and are not readily available to the public.
 
I used Rotella for a year now. First I used T6 5w40 for six months and currently on the second 6 month installation of Rotella but 10w30 T5 blend.

Last summer I changed the oil on a lot of vehicles to a mixed blend of HDEO and PCMO, all within the same family. These HDEO and PCMO blended mixes are not used in cars or vehicles under warranty. They are not used in modern vehicles since most of the oil is API-SM, CJ-4 for the HDEO.

I plan to do the same this coming summer on some of the cars that I change oil.

I had nothing but compliments on how well their engines ran in the heat of summer in severe NYC driving.

15w-40 and some synthetic or conventional PCMO at 5w20 or 5w30 in a mixed blend of 50/50 for the heat of summer seems to be the ticket.

When I changed the oil out, at the end of summer and before the winter, on these vehicles the oil was nice and dirty....lol....the detergent package in the HDEO really loosened up any dirt and liquefied any build up while holding it in suspension.

I'm planning on running another round of HDEO, API-SM, CJ-4 oils this coming summer. I have accumulated quite a stash of Shell Rotella T3, Castrol Tection Extra,(compliments of the Kmart clearance) and Mobil Delvac Super,(Compliments of Mayport NAS, Commissary) all in 15w40.

I plan to use Mobil 1, PCMO with the Delvac, Formula Shell in conventional and synthetic with the Rotella and Castrol Syntec with the Castrol Tection.

These mixed blends, within the same family, should really help the engines to run smooth while cleaning up any build up from stop and go, short trip, excessive idling and excessive summer heat.
 
Thanks mongo for the info. Never thought about that. Heck, you're sayin I could probably put some PYB 5w30 half with another half Rotella t5 10w30 then I take it, as both are same family i.e. Shell products.
 
IMO....First, I don't know what vehicle you drive. Second, I don't know if it would be too heavy for that vehicle. Third, I had called each of the oil companies before I ran the blended mixes to make sure they were compatible.

I did not inquire about PYB since I had a stash of Shell Rotella, T3, 10w30 and 15w40 along with Formula Shell in Dino.

Each oil company stated.....No problem as long as the vehicles can handle the oil weight, their not under warranty, or the vehicle does have an oil burning issue.

All of the vehicles were out of warranty, did not burn oil and seemed to be very sluggish from city driving with Bulk oil changes.

IMO...The HDEO and PCMO blended mix seemed to really clean up any mess and they all ran much better by the time I changed the oil out in early to late fall. They are now running VWB and Napa synthetic combo, PYB and PP, QSAD and QSUD combo or Peak conventional and Advance/Super Tech Auto Synthetic combo's for the winter run. Don't forget...YMMV

I still have a nice stash of Castrol Tection White Jugs of 15w40 and GTX Diesel 15w40, SJ/SL for some Old Jeeps, Ford Flat Tappets and other vehicles that could really use the high ZDDP of these older HDEO.

HDEOs are great oils under certain conditions:

1. Its API grade match or exceed your vehicle's original recommendation. My xB specs API SL, so most would be OK.

2. Its viscosity nearly matches your original manufacturer's recommendation. I'd be OK running a T5 10w30 or T6 5w40 in my xB if I thought it would be a "better" oil. The 10w30 might cause slightly more startup wear in the winter, and the 5w40 might reduce fuel economy a bit. Overall, I wouldn't have a problem if those were the only alternatives for a 5-7k OCI for me.

3. You have an engine (Nissan VQ??) or driving conditions (track use, aftermarket turbo) that are especially hard on oil. HDEOs tend to have a more robust additive package than the latest PCMO.

4. You recently bought a used car with an unknown service history, and think HDEOs offer higher detergent levels and greater cleaning abilities than PCMO. Some say they do; I don't know. Under these conditions, HDEO plus 20% MMO might hit the sweet spot.

To the OP: your neighbor's '94 Toyota truck probably had 10w30 or 10w40, API SG as its original oil recommendation. Under those conditions, T5 10w30 API SM is a good choice, and the longevity of the truck bears that out.
 
I used RTS 5w40 back in 2002 and 2003 back when I had my Jetta 1.8t because it was the easiest to find, however, I crashed that car before it had many miles on it, so I can't say how well it worked.
 
Thanks mongo, and the 98' silverado of mine has the 4.8 v-8 engine in it with over 120k on it, doesnt use, burn or leak any oil. Dont think it would hurt, but I think I will stick with my 5w30 ST oil in that truck as well as in my 11' silverado. Yeah yeahthatsteve, the neighbors truck runs well, used it to haul couple loads of scrap and it runs great. I dont plan to use any MMO in my oil or gas also, feel no need for it honestly.

Yes, where they meet specifications and viscosity requirements. The preferred grade in my old 1991 Audi 200 Turbo was 15w40, and I can't think of any PCMO 15w40s. So, it got HDEO. My old F-150 got that grade in the summer, too, particularly when it was leaking.
 
Currently running Rotella 15w40 in my '62 LeSabre, '70 Newport, '66 Newport, and '66 300.
I also run them in my daily driver during warmer weather. 15w40, 30w, XHD30w, 10w30
