API CF

Hi Enrique,

Please see this PDF, third page. It shows the retrospectivity of the diesel specs.

http://new.api.org/certifications/engineoil/categories/...gineOilGuide2006.pdf

Although they do not explicitely mention the CF at higher grades, they do refer to CD, which is a predecessor.

The CI-4 is backwards compatible to all but the 2 stroke engines where the CF-2 is required.

True, but I would be careful using a CI-4 in a API: CB engine ;-)

I assume EM is relating to Bore glazing in nat. asp. and lightly turbo charged diesels. I'm a bit out of touch, but assume the problem is still about.(in the UK still some old buses in use)EM or others might like to confirm?

Well that would make the API system pretty useless then since each newer category of oil is supposed to be backwards compatible. I can't say I have ever run into something that said you couldn't use a newer oil. I would be very interested to see that.

Well it can be said for practically every classic from before '65, at least for European brands...

I'm not saying that the retrospectivity of API must be doubted, but possible reaction with materials in seals and gaskets is often forgotten in these cases, so therefor it's advisable to be extra careful when using a brand new (high API) oil in a old (low API) engine. This risk can vary per company as each has it's own phylosophy (thus base oils + additive packages) to meet the API approval.

I use CI4 Delo 400 or Delvac MX in two engines which are quite old in design. One being the MB OM616 IDI turbo and other being the HINO W04D DI, the HINO has crossed 178000 miles and the OM616 has crossed 110,000 miles exclusively on Delvac or Delo since day one of ownership and I have not had a single issue of leaking seals or glazing. My engine internals are pristinely clean and my cams hardly show any wear. I have no oil consumption issues whatsoever at all.

Like I said, it depends on OEM and Oil. Mobil has one of the best baseoils, that can help. And my reply was more an advice, not a fact...

What if I use API CF rated oil like say Mobil 1 5W-50 in my Engine that requires minimum of API CH-4

I understand that Mobil 1 5W-50 is fully synthetic and provides outstanding protection.So will this oil work in my case ?
Some of my friends have gone ahead and started using Mobil 1 5W-50 instead of a 15W-40/API-CH4 Dino and they claim engine runs very smooth & all.
Till date I have stuck to good old Delo-400/Delvac MX since my Vehicle needs minimum API-CH4

Thanks,

Use what the mfg recommends and move on. No muss. fuss, or worries.

My owners manual 'recommends' 5w-20 mineral oil,synthetic is an option.

Do I go by the "recommend"???....no.....never do.......I am running 100% synthetic 5w-50.

Trajen..does your BMW MFG recommend to put tcw3 wally world two stroke oil in the fuel tank of your car at fill up.... you claim to use.

Not everyone who knows what they are doing and does all the research... follows the owners manual exactly in every detail. It's only a guide for the lay person.

Can't you *ever* stay on topic?

Explain what a fuel additive has to do with the topic.

You want to use unrated, unknown oil that meets no recognized standard in the industry, that's your problem. Shouldn't expect others to follow you.

Shows the results of not only running the wrong oil, but running it too long.

(Kirk tried the "It's the oil's fault" for the problems. Or rather he tried that here in a different thread.)

Trajan........you were the one who said follow the owners manual.........no fuss,muss, remember. Is two stroke oil recommended in your BMW owners manual....just wondering, since you did say to follow the manual.

Also,you always move off topic,look at all the other threads where you move off topic,I was just following your lead this time.

<<<<<In the post it was indicated the engine has a coolant leak somewhere......Trajan's selective memory loss forgot to mention that.>>>>

AT the end of the bob thread above, this was the opinion of this poster trajan is talking about regarding diesel lube.

Bottom line............the whole thread over there is a bogus/troll trajan.........or at the very least it was not the oil........it was coolant leaking into the oil. The troll is more likely.

You answered your own question.

This thread was moving along nicely, it was informative for the OP, but Kirk once again showed up, changed the direction and more importantly the genial tone of the original topic and responses, he also conveniently added his advertising blurb.

No topic is safe from his mis-direction and trolling...Mods when is enough enough already? Please pull out the big BAN hammer on him, and let everyone post in peace to the original topics. Kirk/inhaliburton/the others, are an embarrasment to this forum, and its posters. Without them here their is a genial and professional tone, with them present, it is mis-direction, attacks and advertisement. These posters/poster have no original thought, as what they post is 'copy and pasted', and passed off as original thought...These people/person PLAGARIZE others thought and work, and try to pass it off as their own...They add nothing except drama...They have been given chances to get along, now it's time for them to go and bother other sites...Their track record of multiple bans from other sites, speak volumes as to their character, or lack their of.

RB, You will be fine using Delo, Delvac, or Rotella. All are great Diesel Spec oils.

Dave and rb2399.......what is the climate where the oil will be run? Colder climates would call for the 5w-- oils. Easier on the engine and greatly reduces dry start engine damage/wear.

What is the exact engine type?

I believe your friends are on to something using the 5w-50.....however a better choice if you are going to use the Mobil products would be..........DELVAC 1 SYNTHETIC. 5w-40.

Delvac 1 is outstanding and the best oil mobil has to offer for diesel engines and some gas engines as well.

This is the mobil link

http://www.mobil.com/USA-Engli...l_Delvac_1_5W-40.asp

Delvac 1 is a great oil, but also costs 50 dollars a gallon. If this is a diesel in the lower 48, Rotella T-6, Delo, or Delvac 1300 would be fine. Most diesels have a block heater for really cold weather.

For piece of mind, I would use the viscosity that the manufacturer recommends and an oil that meets/exceeds their ISLAC/API spec.

Dave

I am from India where temperature range is b/w 40-120 Fahrenheits.
I am still not able to digest the fact that how could engines that require API CH-4 run on API-CF oils.I mean in that case what's the need for higher API specs,just use "cure for all ills" API CF synthetic

CH rating is for low sulfur diesel fuel usage.
CF is for higher sulfur diesel fuel. Both are still current standards.

Nope, API: CF and CG-4 are now obsolete, please post the most recent document:

Whoops, My Bad.

Thanks EM for the most current specs.
