, i got to change the oil myself in my Toyota which has a diesel engine that calls for HDEO oils. List goes from cheapest to most expesinve. Delo 400 is the cheapest BY FAR then the Triple T to the Mobil Delvac 1300 are quite close in price and the Amsoil is double the price of the Delvac 1300!
Currently i have these options:
Chevron Delo 400 LE 15W-40 (Cheapest)
Shell Rotella Triple T 15W-40
Castrol GTX Diesel 15W-40
Mobil Delvac MX 15W-40
Mobil Delvac Super 1300 15W40
Amsoil OE 15W-40 (Uber expensive)


Which one would you recommend and why?
Since this engine is known for clogging up the EGR valve and intake manifold, i'd prefer an oil that "minimizes" as much as possible oil blow by through the piston rings and deposits.
Cold start viscosity isn't an issue since the lowest temperature it will ever see is around 22C. (Most of the time it will be more like 24C - 26C)

Manual says recommended oil is 5W-30 and states that it is recommended because it will allow for better cold starts in below freezing conditions but since that is not an issue for me and i live in a hot place i'd go with 15W-40 as most people do.
Asks for HDEO CF-4, CF or ACEA B1 oils. (It even said you could use CE or CD oils . . . CD ratings are from the 50s!)

Note: I already created a thread in another sub-forum a couple of weeks ago but i didnt get many responses.

I've seen some used oil analysis posted using Amsoil's diesel flavour and even at 40000 miles the oil was still serviceable.
That being said I'm currently using Rotella in my forklift. It's an inline 4 cylinder cat engine.
Devlac,delo and Rotella are all top notch hdeo's so if I were you I'd find one on sale and go with it.
 
Any of these oils should work as well as any other.
Delo is pretty well thought of, so if you find it to be the cheapest, so much the better.
WRT oil life, any of these oils would go an easy 40K in a big rig, but none of them will do that in any passenger vehicle.
Radically different sump sizes and duty cycles.

The used oil analysis I read were posted here. None were a big rig. They were trucks though.
 
What about Rotella T6?

I would not bother with any Amsoil oil unless its their top shelf signature. The others do not make sense to me.

There is Rotella T6 every now and then but availability is limited and i havent asked for the price.

This sounds interesting and I'm too lazy to look.
How about a link or at least a hint as to which date range to search?
It's always intersting to find surprisingly good results from an oil not too many people spring for.
Maybe the cost really is worth it for those who do enough miles to make it pay off?
 
Well-if you're concerned about evaporating/burning off (NOACK), look for the lowest numbers you can find-& I would rule out M1 TDT & T6, they're both known for it (I lose the TDT regularly in the Ram myself).
 
Yeah i was also thinking about getting the lowest NOACK possible since i wanted to reduce oil blow by. Based on PQIA HDEO tests, the best one for my budget would be Mobil Delvac 1300 15W-40 based solely on NOACK. (It also has one of the highest VI Index even though it is not called synthethic, must have some good base stocks for a dino HDEO)

Nothing beats Amsoil OE 15W-40 which has an 8.7% NOACK but it is 2x de Mobil Delvac 1300 and almost 4x the Chevron Delo 400. Not convinced it is worth it since the manual calls for 5k KILOMETERS oil changes. Planning to put a Fram Ultra XG3600 on it (Oversized filter) and run it for at least 2 oil changes since i'd guess a slightly used one would perform and filter better than changing it every OCI and it is specced for way more. (Could be more OCIs, who knows)

Where do you live? Toyota stopped selling diesel cars and trucks in the 1980s in the USA. All the oils you mentioned are common in the USA.

Anyway, Delo costs the least, but it doesn't appear to perform any better or worse than the other major conventional 15w40 oils.

In fact, many people prefer Delo because of the additive pack.
 
Delo, Rotella T3, Castrol, or Mobil 1300. You are likely splitting hairs looking for the "best" out of those. They are all very good HDEO's. If Delo is the least expensive, that would be my choice.

South America.
They dont sell diesel engines because Toyota's diesel engines are thrash IMO. The US market demands engines that are more refined. They still sell these diesel engines all over the world in less developed countries where the market doesnt gives a . . . about engine refinement.
Their diesel engines are very very noisy and vibrate like a street drill and they take way too long to update their engines. This diesel powertrain has 15+ years since introduced, AFAIK there has not been 1 major revision to it. Go wonder!

The advantage i see in the Delo 400 oils is the extra boron and moly but the NOACK is higher and as far as VI goes it indicates a lower quality base stock i guess.
