Mineral , semi synthetic or fully synthetic?

[miko101130]

A little off topic:

Why is it that everytime we have our oil change, our engine response especially during the acceleration in 1st gear is excellent. After sometime, it becomes sluggish and at times you could feel the excellent acceleration as well but not consistent as it was when the oil is newly change. Based from what I have read, oil doesn't degrade as long as we observe proper OCI and the main reason why we change our engine oil is to avoid sludge formation. Based on that premise alone, what could be the reason popular known as "kulang sa hatak"? Is it the wrong type of oil that we use? of course, there are many other factors involved but let us just concentrate on oil in relation to an engine's performance. Your insights is much appreciated.

matagal din sir Retz bago ko nalaman answer sa tanong na yan.. hahaha...

From the First Pouring of a new engine oil into your engine, the oil still contains all the necessary elements that make it effectively promote the proverbial "malakas ang hatak/maganda takbo"

*these elements are the calcium, zinc, phosphorus, molybdenum, boron.... (which makes the BASE"alkaline" of the oil)

*the viscosity of the newly poured oil is still correct.... ( after usage, the viscosity changes, from being either sobrang
"malapot or malabnaw na")

*Over use of a lubricant, i.e. extended oil drains, will cause the base additives to lose their ability to neutralize acids
(reason why pag matagal na ang oil ay di na maganda ang takbo nang sasakyan...)

*oxidation of the OIL (any oil exposed to heat, pressure, and other elements will cause harmful by-products and affects the oils ability to lubricate) Lacquer Deposits, Metal Corrosion

*On not well maintained vehicles there could be water/ coolant contamination with the engine oil... (water and oil don't mix well)

*excessive fuel dilution occurs, the effectiveness of the lubricant is reduced (over rich fuel mixture dahil meh problem kotse)

*excessive fuel soot ( Wrong fuel mixtures especially with diesels and too much air particles sucked by the intake system)

pag bago pa kasi ang oil, all the parameters of the oil from its base elements, pour depressants, viscosity modifiers to other additives are still intact and correct....

after just some hours or mileage, these are already lessened , and as time goes by by using the vehicle these are further reduced to the point that the oil will no longer be able to provide its functions...

--With the use of better filtration and proper car maintenance (fuel/air/oil filter/tune up/spark plug/ fuel ratio) the OCI could be extended safely and reliably.... but no oil will last forever unless its "GTO OIL" hahahaha...

pamatay ung huling sentence mo brad! LMAO! okay, salamat sa detailed explanation. Does this applies to FS oil as well? I was thinking that kung FS oil baka mas matagal ung pag degrade compared sa mineral oil. Hindi ko pa kasi nasubukan ang performance ng FS oil sa engine.

[Gerbo]

Can anyone kind of explain the suitable engine types for the following oil grades:

API CH-4

API CI-4

If FS gagamitin, siyempre mas maganda protection at performance nyan, plus pwede for extended oil changes... dahil sa custom made ang base oil nang FS which is 90% of the total oil volume. Resistant ang FS sa oil oxidation at mas matagal talaga ma degrade ang mga additive package as compared to group III and below base oil...

when i say FS, i mean the Group IV base oils, the PAO.... kaso ang mahal kasi nang mga FS na PAO based... nasa 600 pesos pataas per liter.... parang overkill kase... unless you torture your engine in cases liked drag racing, circuit lapping, extreme towing or off-roading...

[miko101130]

personally kung fully synthetic na pang gas choices would be, Royal purple, Mobil 1, Redline, and yes Idemitsu japan..... these oils are all performer and not that much marketing B.S.... hehehe...

mga sirs, recommended ba ang Shell Helix para sa CRDi Diesel ng STarex.? THanks

[Retz]

mga sirs, recommended ba ang Shell Helix para sa CRDi Diesel ng STarex.? THanks

Ung Helix HX5 it is just rated API-CF. Dapat ung mga FS na API CJ-4 ang sa CRDi VGT ng Starex mo. Ung emission niya kasi ay nasa Euro IV standard AFAIK.

[Retz]

suitable mga yan for high speed four stroke diesel engine. mas bago nga lang ang API CI-4 which is 2002.

[Gerbo]

Found explanation through this one.

It seems CI-4 are for engines with EGR.

most vehicles with EGR are comfortable with CI-4 oils... masyado na kasi luma CF-4... usually mga old school diesel engines ang gumagamit pa CF-4... mura kasi price ng CF-4.... hindi pa magawang obsolete ang CF-4 kasi madameng old engines ang gumagamit pa nito...

In third world countries, more than 50% of oil consumption is still on CF-4 categories... imagine the amount of oil used by mining, agricultural, heavy construction equipment, and other off-highway machines...

Sir, kapag mga modern CRDi engine at least CH-4 ba ang recommended? or CI-4 na?

[miko101130]

Sir, kapag mga modern CRDi engine at least CH-4 ba ang recommended? or CI-4 na?

definitely at least CI-4... suitable to EGR systems and lots of TBN to fight the acidity produced by sulfur in fuel and also provide better emissions...

pero pag super modern diesel engines like those with higher emissions na kung anu anu... SCR/DPF/ etc, CJ-4 is best suited...

Delo® Gold Multigrade
SAE 15W-40
Delo® Gold Multigrade is a high performance, multigrade, heavy-duty diesel engine oil specifically designed to lubricate a wide range of diesel and gasoline engines requiring API CH-4, CF or SL performance lubricants. Delo® Gold Multigrade is formulated with ISOSYN® Technology.

This is what our company uses for the fleet of L300 closed vans (new and old). The problem is, the oil is partnered it with "VIC" filters (C306J or C321).

Anyone with experience using this? Is it even possible to do 10,000 kms with this and a BD28?

Currently, the practice to change oil every 5,000 kms. Each L300 covers about 11,000 kms annually.

Among the API CH-4 rated diesel engine oils, how do you rank Delo Gold, Rimula R3 X and Castrol GTX? and speaking of Castrol, hindi ba talaga magandang brand ito may nababasa kasi akong comment na prone sa sludge formation ito.

I'd rank Shell R3X higher, then Delo Gold. Better Ash, Zinc, Pho and TBN kasi Shell R3X & mas mura ng Shell R3X actually eh vs Delo Gold kung sa gas station ka bibili. Castrol GTX last for me.

Okay, thanks sir ry_tower. noted.

hindi ko na isasali ang castrol sa ranking. that's just me no offense meant sa mga castrol users. pero kung nasa bundok at yun lang ang available eh di gamitin pa rin. pero kung anjan na yung mga mas maganda at marami pa hindi na kasali sa usapan yan. hehe

Thank you sir. Mukhang tama nga ang mga negative commetns about Castrol oil.

"and are intended for use with diesel fuels ranging in sulfur content up to 0.5% weight."

I often see the above phrase in API rating. Is 0.5% weight equivalent to 500ppm?
