your thoughts for use in the IDI?
its time to go synthetic.but i don't want to overpay for something that's to no advantage or perhaps even less desirable for the old school, non emissions classic IDI.

 

unless your going for extended change intervals i wouldnt waste the money on synthetic.

 

its odd,cus i could have sworn when i last researched delvac 1 that it listed CJ-4

CJ-4 Service Category Description

6. Do API CJ-4 oils protect older engines as well as API CI-4 or API CI-4 PLUS oils?
Yes, API CJ-4 oils are designed for use in new engines as well as the existing on-highway fleets. API CJ-4 oils are qualified utilizing several new engine tests that are more severe than those used for API CI-4 or API CI-4 PLUS oils thus defining a new category of oils with much more robust performance than previous categories. API CJ-4 oils are formulated for improved wear protection, deposit and oil consumption control, soot-related viscosity control, prevention of viscosity loss from shearing, used oil low-temperature pumpability, and protection from thermal and oxidative breakdown when compared to previous API performance categories. As always, users should seek guidance from their engine or vehicle manufacturer regarding specific service recommendations.

so that's a point for the turbo diesel.

EDIT!!!

oh i see how i frigged up.apparently there is a Mobil Delvac 1 ESP 5W-40

THATS the one i have been interested in.the "ESP" in the name is important.
here's that one:

compare this one against the turbo diesel please.my bad.

thanks.been all through the research of dino vs synthetic.
this decision has already been made.

 

Either of those oils will be fine. Some engines do better with one oil over another as far as using oil and/or how well an analysis is.

For instance with a Cat engine, I have talked to mechanics that say with Shell Rotella, if the engine uses oil then change to Shell Rimula and the oil usage will stop.

Some Ford owners have no issues with Rotella while others will use oil with Rotella and no problem with another brand.

In the oil and lube forum there are some real knowledgeable guys and the general consensus is that just about any properly rated oil is fine and will do a good job. I've used Rotella T 15-40 since the late 70's, switched to Rotella synthetic when it came out. I use it in all my vehicles, gas and diesel, lawn mower, snow blower. My mower is almost 16 yrs old and still runs strong and uses no oil during the season. I changed the spark plug for the first time this year, starts on the first pull now instead of the second.

 

I used Delo on my last oil change- because it was the best deal I could find! $10.50 a gallon, can't beat that IMO.

 

thats not synthetic bud.

 

Well my auto shop teacher had a intresting point of view on oil hes theaory was the best oil is all of them that meet the requirements of your engine because each one has it own benifits some clean some protect som recondition seals and what not so he suggest use a diffrent brand each time. I just run rottela T because its what I can get cheap actualy right now I got the napa stuff because it was on sale when I went there.

 

They are all good oils, and have used them all. I prefer to use synthetic in everything because it just helps with heat and cold. Plus if you ever lose coolant for any reason or overheat, you will have protection in your engine that will be extremely protective. I learned that the hard way with a truck I blew the coolant out of and the temp gauge went at the same time (of all the friggen luck), but the synthetic allowed me to cool down and not have any problems after repairing the leak. No loss in oil pressure, no knocking, and opening it up for good measure to look around yielded no scoring, bad bearings, or warping. I was really thankful. Plus you will appreciate the help it gives during the cold months, if you have them. The engine will crank over easier and knock less with protection from moment one. That being said, some more "seasoned" engines will encounter seepage with the synthetic oil since it flows so well.

 

So I take it synthetic would be my best choice after im done with the rebuild ??

 

Not until it's broke in ... You must run dino until then else the rings won't seat.

Personally, I have done the testing, numbers and I don't see where Synthetic is worth it in a motor, Dirty oil is the real killer, leaving oil in as long as Synthetic lasts carries lots of filth through the motor.

And don't tell me the filter will filter it out, if you know anything about woven filters you'll know they won't, just look at your oil in the dark with a flashlight and you have all the proof you need!

I run dino in my motors and synthetic in gear boxes.

Thanks Festus Good info...This page is bookmarked!!!

 

I should also point out that I have disassembled a lot of motors and after a time you see what works and don't, Both Synthetic and Dino work equally well in protecting parts from wear as long as it's changed regularly, It very easy to see the motors that were taken care of and those that were not.

I'm not a Dino pusher or Synthetic, To me it's whatever you choose, just whatever you do choose, change the oil regularly!

Some of the cleanest (as in filth and wear) motors I've seen had their oil changed at 3500 miles or less regularly and religiously, it didn't matter if it was Dino or Synthetic.

There are some extreme cases on both sides that each have their own advantages.
For example, Synthetic absorbs heat better than Dino, But it's far worse at dissipating it, Dino absorbs and dissipates about equally, But Dino cannot beat Synthetics lubricity or it's ability to not break down under extreme heat as Dino will.

Does the 6.9L like to drink synthetic more than dino oil or is it about the same. I can't see myself putting $19/gal synthetic oil in my IDI only to top it off every other week and go through a gallon or so before the next oil change.
