What to follow API or ACEA rating?

[Ry_Tower]

^ that may be true but remember ang pinag-uusapan dito is the requirement as per OEM and if babasehan yun plus the actual engine performance, some multigrade, semi-syn with CF rating is still ok IMHO.

Plus many users of shell helix have not reported any engine problems so far so based on actual experience, including mine and my brother-in-laws fleet of ford rangers and Isuzu's, its performing quite well.

However, I also believe that there are better oils out there, for example, top1 SDO whic is semi-syn and same price with helix hx7 as well.

Don't use wiki for any main source of information the site is often wrong. CF oils are not obsolete and are still in heavy use. And for people with older diesels you should be glad they are due to the zinc content of the oil. It's a perfect oil for older engine which there are 100's and 100's of 1000's in the Philippines.

wiki quote

Note: All specifications prior to CH4 are now obsolete and although suitable for some older vehicles are more than 10 years old and do not provide the same level of performance or protection as the more up to date CH4 & CI4 specifications.

The reason it is still marketed in the Philippines and other countries like Thialand and india and the middle east is they have a many vehicles over the 10 year mark. The only vehicle (The wiki was written in 2008)

CF rated oil is perfect for many diesels there, including generators that run on this. But this is out dated oil but not obsolete. Can you run it in L400 yes that engine design is way old enough can you run it in a D4D (No) You can always go up on oil but never down on the specs.

The CF rated oils are for the older vehicles, which there are many. Obsolete oils are no longer made.

ACEA does not apply when choosing your oil that is a secondary thing, The main API rating is what matters,

The other thing about the Shell Helix plus oil it's a great oil for gas engines because it has a robust additive package, but it is not marketed for diesel engine use.

The Shell Helix Super does state diesel engine (probably has a stronger additive package)

http://www.epc.shell.com/Docs/GPCDOC...LCFA2B2%29.pdf

Both would be great for a gas engine but but there are much better oils. I would stick to C-4 and up because it provides better protection like soot control, acid control, thermal and oxidative stability, viscosity control, It's just better oil.

But even the Shell Helix Ultra Diesel is only CF rated as well, with a stronger additive package great for old school diesels.

If you have something 1997 and up I would use something else, Just look at your owners manual.

Thanks dvldoc. I get your point. However I am using an old 4d56 block with newer attachments like crdi and egr (strada 2011). This is the confusing part. I don't know how to treat my engine if its OLD or NEW. As what Ry_tower said tho, the manual only requires CD rated oils, which makes the shell hx7 perfectly fine to use, but if you look at the characteristics of CF oils, its not really suited for CRDI and engines with EGR.

Im also considering the Motul CRDi specific since its already CH and CI rated but as I've said, Im more inclined to oils readily available in the market.

Many thanks.

Sir Ry_tower, where do you get the supply of Top 1 SDO? Whats the rating?

Thanks

I would go for oil with a higher rating than CF, because it offers better protection. Top 1 seems pretty decent.

meself uses delo gold 15w-40 for a 1986 4d56 turbodiesel....iirc API CH-4 and SL rated

for me i will follow manufacturer specs as a minimum.

Top1 SDO is rated CI-4. And I think this is good for engine with EGR system.

last time I bought, it was 270-290 pesos per liter range. this was a month or 2 ago.

sir, san ka nakabili ng delo gold multigrade? and how much? I went to several auto supply but found non. was planning to use it on our vvt-i toyota engine to "clean" it.

[Wh1stl3r]

I use
Mobil Delvac MX 15w-40
Mobil Turbo Diesel Truck 5w-40
Royal Purple 15w-40.
All are CF-4 or later.

Changing from a dino to fully synthetic oil with the same viscosity I've noticed that the engine is smoother, less vibration but at idle I tend to hear what could be tappet noise or piston slap. Any cause for concern?

Djerms – you are now very confused aren't you? To simplify things for the layman, you may look at the outline below:
1) Use your vehicle manual as the basic reference. It tells you the Viscosity rating and the API rating of the oil that you should use for your engine. In the Philippines, SAE 40 and SAE 50 are common. Btw, the higher SAE rating means that the oil is thicker at the operating temperature which is about 99 deg centigrade. SAE 50 is thicker than SAE 40, SAE 40 thicker than SAE 30.
2) The API rating tells you what quality level oil is suited for your engine. API rating of oils for gasoline engines start with an "S" to mean that these are intended for "spark ignition engines". If the manual says use API SF, then using lower grades like SE, SD, SC may damage the engine. But you may use SF grades or higher grades like SG, SH, SJ, SL, SM. (The higher the letter after the "S" means higher grades). The higher grades may be more expensive but they are formulated for more stringent operating conditions to protect your engine.
3) For diesel engines the oils formulated for them have API grades with a "C" before the letters indicating the quality level. For example, your manual may say API CF. The "C" stands for "Compression" ignition engines, meaning diesel engines. The higher the letter after the C, the higher the API grade. So, if your manual recommends API CF for your diesel engine, you may use API CF or higher grades like API CG, CJ, CL, etc. Again these higher letters are more expensive but they have more additives to protect your engine.
4) So the rule of thumb is to consult your vehicle manual and see what is recommended SAE and API ratings. Go exactly for what is recommended for SAE. In the Philippines, it is either SAE 40 or SAE 50. But for API, go for what is recommended or the higher API ratings (higher alphabet designation).
5) One thing you may notice is that some oils have API ratings with both the "C" and "S." For example an oil with an API SL/CF. This oil is formulated primarily for a gasoline (the SL comes first), but it can also be used for diesel (the CF comes after the SL). If used in a gasoline engine, this oil has an API grade of SL, and when used in a diesel engine, it meets the API rating of CF. On the other hand, you may see oils with API CF/SL. This oil is intended for a diesel engine with API CF, but it can also be used in a gasoline engine with a grade of API SL.
6) An oil such as SAE 10W-50 is a multigrade oil while an oil SAE 50 is a monograde oil. During cold temperatures monograde oils tend to be more viscous than the multigrade oils and therefore engines using monogrades are more difficult to start. To be sure, use multigrade oil with the proper SAE rating and API rating.

I hope this helps a little.
