Engine Oil for LC80

[ondoy]

Guys.......

Next weekend, my LC80 (1HD-T, 4.2L, I-6 engine) with 79k at the clock, will undergo its regular ritual of engine oil change. I would like to get your suggestions, most especially from those owning this ride, as to which brand/API grade/viscosity is most suited for this engine.

TIA......

ondoy,

I use Mobil Delvac 1 5w40, API CH4 on my 1HD-T and change after a year or 6k km. Used Delvac MX 15w40 before but changed every 6 mons or 3k km.
Think the Delvac 1 is much better in terms of performance and protection.

jackaroo,

I believe you're in the right track. IMO the best available full synth around is Delvac 1; the only drawback is its cost.

Since cost is very much an issue, what I have in mind is to create a concoction of Delvac 1 and another dino oil, preferably JASO DH-1 rated and a 15W-40 multigrade. I am looking at a ratio of 4.3 liters Delvac 1 plus 5 liters dino oil. This should produce a semi-synth that I plan to use only for 5K km or 6 months, whichever, comes earlier. Delvac MX dino oil is a candidate early on, but was dropped on account that it is not JASO DH-1 rated.

Assuming you're with me on this plan, which is the best dino oil currently in the market that should fit the purpose? Your insights on this would be much appreciated.

TIA......

I too used Mobil Delvac1 in my HDJ-80 in the USA, but have recently switched to Amsoil there (also a synthetic oil).

For regular oil, what Toyota has on their dealerships is a good worry-free bet. I haven't done much research yet on what's really available here in Pinas, but I found that the cheapest Shell diesel-engine oil is only rated for CC --the bare minimum stuff.

Ondoy,

AFAIK it is not advisable to mix oils of different types and makes as this would degrade it's properties not a cummulative type. Oils are specifically blended to meet their desired requirements. Mixing a syntheric with another mineral oil disrupts this perfect balance which leads the the negative side of the scale. Just choose a good, cheap synthetic oil in the market. As this I would recommend either the Petron Rev-X All Terrain or the Caltex Delo Sports or the Top 1 Synthetic diesel oils which are a cheaper alternative then your chosen Delvac 1. Goodluck.

Guys,

Thanks for your suggestions. Finally decided to use Delo Sports synthetic blend, 15W-40, API CH-4, JASO DH-1 ratings. The LC80 should be happy with this engine oil.

On one hand, I still think that mixing Delvac 1 with a conventional oil is a logical idea, what with this statement, in reference to the technical specifications of Delvac 1: "It is also fully compatible with conventional oils." What matters most, I think, is the choice of the conventional oil that should not enhance additive clash with those in Delvac 1. For the moment, I will put this idea at the back burner, for further evaluation.

How much is a Delo Sports synthetic blend?

Ilan liters kakainin ng LC80? my LC90 kasi is eating up 7 liters

OT: paging Sir Kimpoy and Sir Olive may Petron Rev-X All Terrain ba sa Pampanga? location po? Tnx tnx

Jeepcruizerph, the 1HD-FT engine needs about 9.1L, if I remember correctly.

On a side note, did you happen to smell the oil and exhaust? Smells like tutti-frutti gum.

[jackaroo]

ondoy,
That's a first, mixing synth and mineral, but not sure it will work as intended. The synth side may be too little to make a difference. Think the "synth blends" are basically mineral base oils with synth additives so i'd prefer just a plain mineral oil changed often if a full synth is not an option.

roydok,
The Top1 synth is really a blend- says so on the can's fine print. Kinda misleading but the price gives it away.

Sir Ungas what do u mean by this? is it a good sign or not?

baka kasi yan gagamitin ko mamaya Caltex Delo Sports 300 pesos per liter daw...i cannot find the petron Petron Rev-X All Terrain here sa pampanga kasi

[xox]

how come you guys spend so much on your oil? I just use Delo 500 SAE40 for my LC80. P300-350 lng per gallon. Wala naman diff

No, not a bad sign. NAtuwa lang ako sa amoy nung oil. Kakaiba kasi. Lahat ng oils na naamoy ko either walang amoy o kaya mabantot.

Dami dito malapit sa Petron namin All Terrain *267/liter.

ah oks oks tnx tnx a lot Boss Ungas :-)

sayang mas mura pala Petron Rev-X All Terrain

I can say i dont spend too much on oil as I still used mineral oils and change every 5000km (if i had lotsa extra PPP, i wouldnt mind using synth every 5000km) and buy by the bulk if possible. But i take my time to take into consideration the specs of the oil to be used with what the manufacturer recommends. I usually choose 20W-50 or 15W40 weights and with the highest possible API rating. Oil is very much the lifeline of the engine and i've already seen a lot go bad (sludge, loss of pressure, leaks, etc) because of lack of maintainance and some because of the wrong grade oil used... SAE40 is ok but i prefer the multigrade oils, especially since operating temps varies in our day-to-day drives (i.e. in short distances where the engine hasnt warmed up yet so the 40W isnt in its optimal range yet, or long drive with high speed and revs). Oil type becomes even more relevant when the engines are turbocharged or modified as these usually run higher temperature and are under more stress.

Its really hard to judge the differences in oils used and their effects without deep probing into the engines for the long term effects and by doing an analysis on the oil after its used.

[jackaroo]

Well said vinj!

In my mind, why scrimp on engine oil after investing a million pesos++ on your suv? The oil is the only protection you have against metal abrasion specially in turbo stressed engines.

My LC80 has 139k mi. on the clock OK pa ba ang synthetic sa ganun mileage? Right now i'm using mineral base 10W40 instead of 5W30 listed on the oil filler cap. Thx :confused:

got ur points, was just wondering if multigrades really make a diff in our country bec. the W stands for winter right, our temp here even during night is far from winter temp, just wondering if it really does make a diff

[vinj]

With 139K on your odo... try to use one with a thicker viscousity (i.e. 15W-40 or 20W-50) since your gaskets may not be as good as before. Thus, thinner oil may leak through more likely.

Xox, on the difference of the effects of using multigrade vs. monograde oils in our country, i have not seen any independent tests nor have personally tried since i never used mono before. From what i always think, its the trucks/commercial vehicles with a more narrow RPM band that use monograde usually since their engine operation speeds are more or less constant.

The W does pertain to "winter" and in our case, its also known as the cold engine operation viscousity/effectiveness. Thus, this comes into play when the engines are newly started and not yet up to operating temp (i.e. on short stop-and-go drives) and as we know, most wear and tear to the engine also occurs during start-ups and when its running cold. Thats also why some cars tha trun synth oil with lower viscousities experience less start-up clatter as well.

Another oil for Toyota's 1HD-T engine:
An oil analysis done on the delvac1 after 5k km showed higher viscosity- over the 125% max- think this is due to soot build up. Even a synth oil can't handle so much soot from poor quality fuel. Think it would be better to change more often, as in every 5k km.

I've switched from Delvac 1 to Conoco's PowerD 15w40. Price aside, the Power D carries an API CI4 plus/ SL, DHD-1, JASO DH-1, ACEA E3/E5 rating. Plan to test the oil after 3-4k km.

Anyone interested in buying my delvac 1?
