thank you sir. ano ba main advantage ng CI-4 plus compared sa CI-4? ano ba dinagdag sa 'plus' ng CI-4?

thank you sir. ano ba main advantage ng CI-4 plus compared sa CI-4? ano ba dinagdag sa 'plus' ng CI-4?
What's the difference?
How is CI-4 PLUS different from CI-4? Here are the highlights:
Test data used to set the CI-4 PLUS standard comes from a single OEM — Mack Trucks and its T-11 engine test — rather than a program developed and sponsored by the industry as a whole.
The key additional benchmarks for CI-4 PLUS are a thickening test, i.e., how much soot the oil can handle before turning into sludge; and a shear-stability test that now runs for 90 cycles, rather than the 30 cycles required by CI-4 standard.
CI-4 PLUS is designed to deal with a certain set of conditions. “The only way to truly know if you need this oil is to analyze the oil. The oil analysis process is the only way you'll get — with 100% certainty — the information you need to make that decision.”
CI-4 PLUS is only going to benefit a limited percentage of the market, which is why fleets need to decide for themselves whether or not they need it.
CI-4 plus was put into action because the different large engine and truck manufacturers have different needs and requirements for lubrication, the truck and engine industry were becoming expensive for them to test and certify their oils individually so they set up a meeting and came up with a category specifically made for the heavy duty engine and trucking industry...
usually an oil spec will need 3 years to become the standard, but CI-4 plus was put into effect after only 12 months because most of the test was already pre-conducted by the engine company MACK EO....
basically CI-4 plus was made to conform to the lubrication needed by the trucking industry in terms of soot handling and shear stability.... because of the new emissions imposed, the EGR and other emission control put a new requirements for lubrication on the design of the engines used by the heavy trucking industry...
sir Retz, from what i have read over the internet, CI-4 plus is designed and developed by engine makers for trucks and heavy equipment that solves their own lubrication requirements...

Thanks for the info sir. So hindi pala applicable sa atin mga passenger vehicles ang CI-4 Plus. Pati na rin ang CJ-4 which is below 500ppm dapat ang sulfur content ng fuel. So CI-4 lang talaga and mga earlier API rating na CH-4 upto CF.
^ But CI-4 Plus can be used in passenger vehicles esp if you want extended oil intervals. Mas bagay siya for that. Basta better pa rin CI-4 plus kesa sa CI-4 lang but kung costly naman kasi yung napiling mong oil, maybe hindi na nga dapat. Puwede na CI-4 na lang.

Noted sa inputs mo sir ry_tower. Saan ba magandang website that has a list or a chart of all API ratings and then may explanation na rin doon about the API standard. Paki post lang link. Thanks.![]()
sir ry... mura pala bd28 natin sa pilipinas.. sana hindi tumaas prices dahil sa demand ngayon... hehe
sa ebay... its $28+ tapos 7+ shipping.. tapos papunta pa ng pilipinas.. hehe
calledup again kanina.. wala pa stock
hahaha... malapit lang ako sa volmax... binondo din ako... pag dating ng delivery truck ng baldwin.. hindi pa nababa sa truck.. sugurin ko na yan.. hehe just kiddin..
nakulitan na siguro yung sa tindahan... hehe araw araw.. may tumatawag.. boss may bd28 naba tayo? hehehe
Bro, basically pag nag pa oil analysis ang tinitignan is Elemental wear analysis, yung mga iron,lead,copper,silicon,chromium etc, na nasa oil mong ginamit, para malaman ang wear sa engine, pero it needs to be done in pattern, kung isang beses lang oil analysis hindi kasi conclusive unless na several times at regular interval ang analysis para meh mag emerge na pattern...
tapos yung TBN (total base number), kung ilan pa natitira na TBN to fight the acidity
then kung gusto mo pwede din yung (TAN) total acid number naman,
Then lastly yung mga fuel count at soot count at coolant count on the oil...
ang bilis kasi na over shadow ang CI-4 plus nang CJ-4....
minadali kasi yung Oil category na toh for the fast changing emission regulations which the engine manufacturers can't cope with.... it was designed in parallel during the development of many engines, so nung natapos design nung mga engines, the oil category is now late for emission standards...
CI-4 plus is definitely created and intended to extend oil change and improve soot handling on engines requiring that specification.
Got a response from Royal Purple Technical Manager for international markets. Will post it tomorrow, am on mobile now. Basically, what he is saying was that CJ-4 oils are okay for 500ppm diesel fuels (Euro II, which the Big 3 has) as the TBN is still within 20x of the sulfur content. That makes using Euro IV fuels (Unioil and Eastern) much much better. But since CI-4+ oils has a bit more of the anti-wear properties, it is still preferred to use this for additional engine protection. But for protecting both our engines and the environment, CJ-4 should be the choice...cheers
actually, yung post ni miko regarding sa oil selection is a quick guide. 1-2 pages back ata.
1. sulfur content in diesel oil (500 ppm ang boundary usually)
2. emissions-compliant ba yung vehicle (DPF, SCR, EGR, etc.)
^^or sariling compilation mo yung data na yan.....makagawa nga rin ako ng local file ko. sa tagal kong nagresearch dito eh diko naisip yan. puros download lang ng pdf etc. hehehe
