ok, bought 2 gallons of delo 400 15w40. I like trying different oils, have read some good things about it on these boards and others..

Going to use it in my 3.2L 24V V6 (SOHC version) found in isuzu rodeos/troopers.

I was under the impression that it is a regular dino oil with a very good addative package. but the front of the bottles has a little logo on it- says "super syn technology" or something like that- is delo 400 formulated with some form of synthetic?
 
they use GP III oil which can be called a synthetic but is not in the same class as a PAO or ESTER synthetic but delo is a good oil with a robust DI package and if vis is correct for you car should give no trouble.

The term is closer to iso syn I would say it is there trade name for their hydroisomerized {sp}base oil. Kinda like clear base or pure base. Chevron calls it a gpII + oil .Good value for the money.
 
cool- so it's better than regular ole dino, nifty. If I could find some delvac 1, i'd prolly run it. figured i'd try the delo for now.

at about $7/gallon, and better than regular dino, I'd say the delo400 is an excellent bargain.
 
and yea- it's "ISO SYN" i'd forgotted what exactly it said on there.

I think it might have been "supersyn" that i read on the 10W30 wallytech pure synthetic, (which I understand is made from a notch lower than POA/ESTER synthetic bases)
 
ok- another question about the delo...

I see, a lot of diesel OCIs are typically MUCH longer than traditional gas engine OCIs... tens of thousands of miles... running on stuff like delo 400, delvac 1300, valvoline blue, etc...

Now- I have to take into consideration, that diesel engines, have HUGE oil capacities, (measured in gallons, not quarts). as I recall, a cummins in a 1 ton is something like 6 or 8 gallons, significantly more than my regular ole gas engine, over the road trucks, are soemthing like 20-30 gallons as i recall... So, obvously, the capacity plays a large part in the OCIs.

Also- The milage is different for over-the-road trucks, as they run primarily highway miles, not in-town miles. so again, milage becomes a different amount of "wear-per-mile."

But then again, the engines, are MUCH higher compression (in the order of 30 to 1, as apponsed to a gas engine, around 10 to 1), which would put more strain on an engine.

but then again, again, gasoline engines generally run higher RPMs (2-3X the revolutions/min, big detroits and cats redline under 2k, 1 tons around 3k, where our little gas engines, are cranking, 4.5k, 6k, 8k, redlines etc)...

so many factors...

basically, the question is- Do I treat my OCI the same in a gasoline engine using diesel oil as I would have using regular gasoline oil.

I'm assuming yes- because it seems like the factors above pretty much ballance out.

seems like if there was some "secret life" in diesel oils that gas oils didn't have, there would be BITOGers all over reporting 30k intervals on them.
 
Semi engines hold arount 12 to 15 gallons of oil .The Ford powerstroke holds 15 quarts .The compression is around 17 to 21 to 1 on diesel engines.The only safe way to extend oil changes past manufacures recommendations is by using oil anaylsis. If the engine is in good shape then gallons of feul used is a way to determine oil change intervals. Heavy duty engine oils have higher additive levels and are formulated for longer life than passenger car motor oils
 
mdocod - let me know how this fairs in your 3.2L rig; I have the same beast in a 97 Rodeo.

You know, I use the Delo 400 in my 01 Dodge Diesel - never thought of using it in the Rodeo. Always thought the Viscosity was too thick.

Let me know how it sounds/runs with it.
 
on the subject of heavy oils in the rodeos...

I have run a fair number of 10W40s, and even recently during summer months I did a test run with some 20W50 supertech for about 1500 miles (at less than a dollar a quart, short OCIs don't bother me)...

here's what I notice:

when running 5W30, 10W30 type oils (recomended weights). I tend to have a much louder startup, the clicking is very loud for about 20 seconds (louder the colder it is). The oil pressure is usually less accross the board (at startup, and ramping through the rpms, which indicates, in theory, that it might be flowing better)

when running a 20W50, the startup pressure is pretty high, I wouldn't suggest ramping up the rpms much on the cold oil, is probably a good way to kick open the bypass valve. even after the oil is at temp, it has a higher pressure reading than a 30wt, which makes sense.

I have run 15W40 delvac 1300 (ran it about 2500 miles). It seemed to generate as much oil pressure as the 20W50 supertech, but was less likally to generate start-up loud-ticks. I would imagine that the delvac 40wt is probably almost as beefy viscosity wise as the supertech 50wt.

My feeling, is that, as long as you don't use too heavy a "W" rating for the tempuratures you might encounter, there is no reason to worry using a heavier weight oil. To be on the safe side, don't ramp up the rpms when the oil is cold.

an interesting thing to note- I once used a 5W50 quaker state synthetic, it registered no oil pressure at idle, and ramped up far lower than dino oils in general, I think synthetics really do pump a lot better. (noticed same phenomenon when using other occassional synthetics also)

In my experience, the heavier oils, tend to make less engine noise (ticking).


after I try the delo, I'm going to go on a search for delvac 1 to use over the winter months (lower W rating, better pumpability, pure synth, could run a longer OCI)

i'll try to keep my experience with this engine and oils updated on these forums occassionally. as i'm cetainly not the only one out there with an infamous ticker.
 
I have a '99 Trooper (the one that's famous for consuming oil) that I had run 10w40 & 10w30 dino in for years. It always consumed around a quart per 2k miles, (this is normal for the 3.5 v-6). Apparently, there was a oil control ring issue with the early 3.5's. Well, I switched to Delo 15w40 (with half bottle of synpower) and voila! No oil usage. At all! Ran the last change to 4k miles. Didn't use a drop.
 
Your original assumption about oil capacity is a big part of the formula. Cummins puts out a chart of how many gallons of diesel burned per gallon of oil capacity to determing oil change timing.
 
For those who can't afford synthetics, Delo 400 provides an excellent alternative and is perfect for normal weather driving and will perform as well as any synthetic, only in extreme conditions would I give synthetics an edge.

I use Delo 400 in Honda Civic VTEC which are used for weekend races and 4 stroke motorcycles as well under really hot and dusty conditions and they perform quite well.
 
Delo is not just for diesels yet most other automobile oil is suitable. I use DELO when I want the very best Additive package for cleaning & protecting your engine,like the Redline of petroleum oil.Another good cleaning oil I heard is Castrol 20/50 GTX.But I would always use the DELO if available.

All we use at work is the Delo 400 15W40- I run it in my cars and trucks since I get free there. Anyway, we use it in our Diesels and gassers with great results. Oh and if it helps anyone, the Cats in most freightliners hold 28-32 quarts.
 
Most "diesel" oils carry a spark ignition rating, such as SL (Delo is SJ), which most owner's manuals focus on. No worries mate. I will try Delo 15w-40 in our Trooper next time. Have about 2/3 qt usage over 4K miles with Rotella T Syn.
 
Coming from a syn user(Motul & pro-GC), the only dino I prefer and do stash is Delo 400. It is my only choice for dino oil(for the beater 190E).

If you mean the DC 1 ton trucks with the Cummins 6 thes hold about 12 quarts or 3 gallons. The IH 444 in the Fords holds up to 4 gal., and the GM engines typically are at 2 gal. in these "light' duty trucks.
 
Hey mdocod, I just put the Delo 400 with Purolator premium plus oil filter in my wife's 03' 3.2 V6 Isuzu Rodeo (we share the car pretty much) and have been very impressed..so far about 1,300 miles and there's zero consumption and the motor feels very smooth running down the highway...Was previously using M1 and it would consume from a 1/4 to half a quart within 1000 miles of run time...A total of 3 OCI's with M1 10W30 twice and M1 15W50 once...Even the M1 15W50 was consumed at a rate of 1 quart in 3,000 miles.


I'm going to try some different oils as well to see how they do but for now the Delo will have a big checkmark next to it on my list of oil choices.
 
I have been using Delo 400 in the 2nd ARx treatment in my 1990 Jeep Comanche 4.0L. It is very smooth and the oil consumption is zero. The oil got very black within 200 miles. I am not certain if it was the ARx treatment or the detergency of this oil, but I am sold on this product. I am going to use it in the Jeep during the warmer months and Havoline High Mileage during the winters. My old Jeep starts very easily with the Delo during the NC summer months, but I am a little hesitant to use it in the winter.
