Which Diesel Engine Oil...

[roydok]

Congratulations on your great informative site. It's my first time to post here.


Which is a better diesel engine oil for use with my diesel Land Cruiser 100? I plan to use mineral oil since I change the oil every 3,000 kms.

1. Caltex Delo Gold Multigrade 15W-40 API CH-4/SJ/ACEA E3

2. Castrol GTD 15W-40 API CH-4

3. Shell Rimula X 15W-40 API CH4/ACEA E3

4. Petron Rev-X Trekker 15W-40 API CH-4/ACEA E5

5. Sea Oil Deo Turbo Max 15W-40 API CI-4/SL/ACEA E5

6. Mobil Delvac MX 15W-40 API CH-4/SJ/ACEA E3

Your comments are highly appreciated. Thank you.

the higher the API rating, the better. Petron's Rev-x All-terrain is fully synthetic, though priced like mineral oils.

i use Castrol on my rig,
no problem so far.

roydok,
Is that your post or a quote from someone else's query? I know you're an informed "oil spec" guy.

jackaroo,

The post did not came from me. I guess there may be a computer glitch or something when someone has posted. Just look at my no. of posts and it's 1477. The original poster is also 1477. My current post right now if I'm the original author should be 1478. I already informed the webmaster about it. Anyway the question is still very valid.

I'm sorry roydok but I'm the original poster. I guess it maybe a server error. Thanks for all your comments.

If I would use fully synthetic Oil for my Pajero does it mean pwede ko iextend yun change oil intervals ko to let say 10,000 kms? Comments please as am very confused about the Fully Synthetic Oil.

[roydok]

lancelot,

Iyan po ang sinabi sa akin ng isang Mitsu service adviser. If you will use their Mitsu Turbo XP synthetic oil ay every 10k na palit ng oil pero every 5k palit oil filter.

[notEworthy27]

so ibig sabihin kapag fully synthetic ang blend mas matagal? is this true? im currently deciding kung mineral or fulyl synthetic ang gagamitin.

[roydok]

Generally mas matagal talaga life ng synthetic compared to mineral since it resists degadation better than mineral. The only downside is the cost. If you can afford it then the better. If not then mineral oil with a regular oil change every 5k will do.

So mga sir : a fully synth oil with a lower API rating is still much better than a mineral oil with a higher API rating? API-CI4 na po daw kasi yun SeaOil Deo Turbo Max at yun Caltex delo Gold? Medyo nalilito nga din po ako.

I used Delvac MX 15w40 on my LC100 for the first 24k km then shifted to delvac 1 5w40 full synth. On delvac MX, use to replace every 5k km or 6 mons but on delvac 1, will do max 1yr or 5-7k km interval.

Since an oil change requires 11.5L in the LC100, there's a huge price diff between mineral and full synth. I think mineral is ok if you only do low speed driving but, if you travel a lot (high speed) then a full synth is better protection for the turbo.

The toyota oil filter for the 1HD-T engine is a twin element type, meaning it has a full flow and by-pass filter combined. This type can easily handle 10k km use but they recommend only 5k km under extreme use. The point is- a bypass filter can actually extend the life of an oil by removing finer impurities thus less wear on the engine's internals.

IMO, any of the oils mentioned would be OK, just stick to the proper service intervals and if your engine is turbo, dont forget to cool it down before shutting off. Use one with at least a CH-4 rating.

With synths, if you do extend the drain interval, you still have to change the oil filter at 5000km. Even if the oil keeps its viscousity and lubricating properties longer, the dirt from daily useage will still be there. I've tried extending my oil change in a gas sedan to 10,000km once with synth oil and NO oil filter change and what i got afterwards was basin full of muck.

Given the choice, i still prefer to use mineral then change every 5000km (i use Delvac MX in my pick-up BTW). You can also try semi-synths then change every 5000km as well. It'll give added protection but costs half the price of full synths.

it's the other way around, a mineral-based engine oil with higher API rating is better than a fully synthetic engine oil with lower API rating.

among the choices pipiliin ko yung sa Sea Oil...personally, i would stick to the engine oils of the big 3 at sa mobil...subok na eh...gives you peace of mind...

scanner, Delo Gold Multigrade is API-CH4, Delo 400 yung API-CI4(di pa available locally)

[lancelot]

Chieffy,

In the oil database forum you mentioned you have delo sports semi synthetic blend?

Do you have this is your Station?

Roydok,

Di ba if you change filters every 5k, that means matatapon at least 1 liter of oil?

[lancelot]

Roydok,

Pre, saan mo natanong yun price ng seaoil deo turbo max na 115.

I tried asking seaoil here in sj 135 daw/liter.

OK ba siya IHO?

[scanner]

Thanks for the clarification. Subukan ko SeaOil Deo Turbo Max next oil change ko.

[notEworthy27]

san ba yung pinaka malapit na seaoil gas station nam ay oil change serviceS? im at novaliches.nearest gas station is mindanao ave. pero walang oil change. san meron? so is seaoil oil safe to use. tested?

Definitely magdadagdag kayo ng oil pero depending on the side of the oil filter of your vehicle it may be equal to 1 liter or less.

115 pesos po as per price sa Sea Oil McArthur Highway, Potrero, Malabon and Sea Oil EDSA near Q.A. Pero syempre nagbabago price niyan depende sa location. I recall both service oil changes.

By the way, I am not promoting Sea Oil as a product. I'm just stating the facts on some new products in the market. Sana nga sumunod na din Big 3 at upgrade nila diesel oil products to the current highest API standard. It's healthy for all of us users.
