Best Diesel Engine Oil and Replacement Oil Filter for Isuzu MU-x?

[leoblack9]

If you're asking which is best then go with the Isuzu casa's rebranded version of Caltex Delo Sports 10w30 (it even has a D-max on the cover!) or IGMO Multi-Z 10w30 and Isuzu Genuine filter (Not the Isuzu "Best Value" parts, those are different and produced in their Thai plant compared to the Japanese manufactured Genuine part).

Most economical option I'd recommend Delo 400 MG/MGX 15w40 or Mobil Delvac MX 15w40 + a Vic C-529

The hint here is that all of the recommended oil above (except the Multi-Z, which was preferred over the older Besco 10w30) is in the manual.

^ try mo delo 400 mgx. It's supposedly the best in the budget delo line-up. Although hindi sya fully synth variant.

I personally Just bought 7 liters of them to use on my next oil change. Will pair them w/ a baldwin double filtration oil filter.

do what you gotta do so you can do what you wanna do

Amsoil 5w40 signature series un inilagay ko last week nung nagpms ako sa bahay. Sobrang smooth.

Besco 10w30
Multi-Z 10w30
Delo 400 / Delvac MX 15w40

In that order. You don't need anything else. Isuzu Mu-x and D-maxes are very economical in terms of maintenance. You just have to change it very frequently because you don't just change the oil, you remove the accumulated particles and contaminants suspended in the oil that is smaller than what is captured by the oil filter.

The only advantage of full synthetics is longer OCI and better high temperature protection for your turbo bearings. Change every 5,000km if you are idling in traffic every day, that environment is very hard on the oil. You dont just count the kilometers, you count the hours of your engines idle time.

I myself just run the Multi-Z (since its a rebadged Caltex Delo Sports 10w30 semi-synth) and change every 10,000km or 6 months since I hit the expressway a couple times a week. Diesels are happy with long hard expressway drives.

what does the owners manual require? api-ch4 ci4 cj4? also what is the oil change interval in the owners manual?

As posted by someone earlier in this thread, the Isuzu 4JJ1 has a minimum ch-4 requirement, which all of the oils above exceeds minus the Besco which is still CH4. They're all listed in the manual so I'm merely parroting it for people too lazy to read on their own.

Also the OCI in the manual is 20k. 5k for severe service. I don't drive my truck on the expressway 7 days a week so nope not gonna run it to 20k.

Un fc ko from home to work balikan using delo400 13.5-14 kpL ( 60 km). Sa amsoil 5w40 ss 16.x kpL.
Ramdam sa acceleration iba talaga kaya kita sa fc.
Un frequent oil changes may masamang epekto din naman. Nadiscuss to sa BITOG, nagkakaroon ng wear and tear during oil change dahil magkakaron ng delay un pasok ng oil sa engine sa unang andar dahil popondo muna sa filter un oil which is pansin ko din naman dahil personal na ako ang gumagawa ng pms. Kaya pinili ko ang amsoil para extended un drain interval.

Nabasa ko din yan sa Bitog. May 1000km na "running in" period yung new oil for it to form a protective layer for lesser startup wear. Okay lang sakin yung yearly changes sa gas engines but not diesel engines since diesels have a tendency to accumulate a loot of carbon or soot in the oil.

Dito kasi sa pinas hindi naman purong highway yung kalsada dito parang sa US. Its mostly urban roads with a lot of stop and go traffic kaya hindi ito magandang environment for diesels with turbos and egr. A lot of idling and low speed commutes = carbon buildup.

Think of it this way, yung carbon particles na smaller than 95% microns ay di nakukuha ng oil filters, kelangan mo ng bypass filter para mafilter yan. So unless magpakabit ka nun iikot at iikot yang particulates sa loob ng makina mo, causing wear here and there. Kaya if possible I would just suggest a semi-synthetic and change it frequently around 5000km / 6 months if its driven everyday in Manila traffic.

The proof of this concept is those people with older cars who run the cheapest mineral they could find and change every 5k or 6 months (or even 3k / 3 months!). I've seen Pajeros that are at least 10 years old but the engine sounds so smooth that I could have thought of it as brand new.

Kaya pinablank ko kagad un egr ko para di mabilis ang carbon build up. Magkasing kulay lang un 5k km oil ng mux ko at mazda3 skyactiv ni utol.
Bihira din naman kasi ako matrapik. So far 80k+ km na din naman un oto ko, magkasing tunog pa din naman makina nung mux ng tropa na may 5k km odo

bro ano engine mux mo? thanks sa inputs about using amsoil. currently im using delo 400mgx paired it with js akasahi sa np300 so far better than other mineral i have tried.

2.5 un akin. Tama naman un feeling mo, sa lahat ng mineral na nagamit ko pinakamaganda yan delo400/delo400 mgx. Sa fc lang magkakatalo vs lighter oil. Pede din iextend ang drain interval nyan, ang claim nga ng chevron kaya gang 80k km. Hehehe! Pero un mga buses dito sa tin every 30k km ang oci, delo400mgx ang gamit.
Yan ang gamit namin sa frontier 2.7, every 10k km oci. Dati delvac mx gamit nun, nakumpara namin ng tatay ko na pagdating ng 5-6k km na gamit un delvac lumapot na, un delo400 parang bago pa kaya nagstick na kami sa delo400. Pero itong next oil change bumili ako ng amsoil turbo truck hd 15w40 100%synthetic, malalaman kung alin ang mas maganda. Sa April pa namin ilalagay

Eto kulay ng oil ko, 1k km na natakbo. 84k+ km ang odo. Nakakatuwa kasi matagal na umitim ang oil kahit diesel engine, tingin ko lahat ng crdi engines ganyan na.
Di katulad ng lumang diesel engine na isang gamit mo pa lang maitim na ulit

Sa pagkakaalam ko pag umitim kasi normal yan sa diesel. Ibig sabihin lang naglilinis agad yung langis. Sa gas car ko oo matagal umitim, since cleaner running naman talaga pag gas.

Sa tingin ko same lang yung delo sports at multi-z, since partner ng Isuzu dito ay caltex in making their lubrcants.. just like Toyota with Aisin/Idemitsu and Suzuki with Total.

Heck, sa label nga ng delosports 10w30 ay Dmax, sa 5w40 Alterra naman.

Hindi totoo un. Mas lean burning na kasi ang mga crdi engines kaya matagal na umitim ang oil. Kahit nung multi z pa ang gamit ko matagal din naman umitim.
Ginamitan ko din ng multi z un frontier namin, di pa un crdi. Umitim kagad ang oil.

Ganyan din D-Max ko, pero yung Fortuner namin may langis na tulad ng Delvac1 na umitim agad, tinry ko yung Multi-Z 10w30 sa Fortuner, after 2 weeks light colored parin.

Compared sa Amsoil gaano katagal po ito umitim sa Mu-x niyo?

[kkreuk18]

1st time ko pa lang maglagay ng amsoil. Nasa almost 1k km pa lang un nasa pic. 2 wks pa lang. Kaya hindi ko pa alam.
Totoo din naman na nasa oil din. Kasi sabi ng tropa ko na nakapajero bilis umitim ng shell helix at Castrol, kaya nagstick sya sa delo

which shell helix? helix is normally for gas but some can do api-cf and not the latest api-cj4

shell rotella is for the diesels
