Toyota motor oil

Also while I'm here what's a good oil filter to use on a 1HZ ????

Phil R,
As far as I'm aware diesel oil and petrol oil are diffrent, apart from the viscosity beng diffrent I think the diesel oil also has a detergent in it to wash away the carbon deposits you naturally get in diesels. This problem will diminish with the introduction of ultra low sulphur diesel.Keep the shiny side up

Just had first service on Diesel Prado and Toyota dealer put Valvoline sticker on screen.

Lots of info on the forum - do a search

Thanks Ken

I tend to use a bit of oil, I get a few puffs when taking off and no doubt use burn it
at higher speeds but less noticably, Do you think a heavier oil (20/50) could hang on the cylinder walls causing exessive oil use.

Phil,
I made a few comments on another Forum Item re Nissan Oils.(5892)
I can add to previous forum comments about oils by saying that lube oils are either mineral or Synthetic & in some cases a combo. The raw oils during manufacture have limited properties. It is the addition of a range of additives which give the oil their performance values.
eg: Anti-sooting, Detergent, Anti-Foaming, Anti-Friction / Anti-wear substances to allow greater range of operating temperatures. The additives also allow the oil to be used over the Viscosity Index range as you have quoted 20/W50 SJ/CF. If you go to hot areas and or your engine is badly worn, it may be in your interests to run a specific higher range viscosity than a broad band 20-50. Alternatively If you are going to be down in the Snow for a season it would be appropriate to drop to a lower Band (15/W 40 etc)Also the additives in oil don't last forever, they can break down if you don't change it. It is a case of fit for purpose hence if know there is a bit of oil use, high KM & you want to go to the snow/dessert the specified Factory oil for your particular vehicle & engine (Toyota-Nissan etc) may be OK but could also be marginal for you, hence depending on the situation & if not sure I would be motivated to have a chat to the Oil Co Sales Engineers for Lubrication products. Certain Diesel Engine oils can be used in Petrol Engines but generally speaking each type of engine has oil specifications that are quite different & one should not experiment but get advice from Oil manufacturer's. The additives do vary & are limited in each application.
Sounds a hassle to get the right oil but it pays off.

The Toyota branded oil is just a common oil like GTX 2 or Valvoline XLD. It is packaged locally. Don't use it. Even the dealers don't use it - they work out a cheap price from Mobil, Valvoline or whoever and usually use a 15W40 oil thats OK for both diesels and petrols. In a diesel you should use 15W40 unless in the snow, where a thinner oil is better. The 20W50 takes a little longer to get around at startup and thats when most wear occurs.

Hi
I used it for yonks in my turbo diesel, because it was cheaper than buying Valvoline super diesel. Back then Toy oil was 15/40.
The SAE rating says it all, CF is the diesel rating. If you have a turbo, then 15/40 is the thickest you should use though. Consult the owners manual and the temp charts for 20/50 are minus 5 to greater than 35 deg/celcius.

I would give the 15/40 the nod only because it will be easier to get up on top in the mornings. Have used 10/30 before in Mobile Delvac, but it ran out the main crank seals, and after switching back, was ok again...

Hi all.

Many years ago in my younger days I worked for Shell and did a course in vehicle lubrications, and this is what I was told. Take it for what it is worth.

In the old days before multi-grades were al the fashion, in summer we used a heavier oil, in winter a lighter oil.

Since the advent of multi oil we used that summer and winter. The reasoning behind this was that the oils BEHAVED differently in different temperatures.

For example, a 20/50 multi oil, in hotter conditions the oil acted as a 30, 40 or 50 grade viscosity grade oil depending again on the temperature of the engine and ambient temperatures, the reverse applied to colder temperatures.

But the most important point to be pressed home was that when the engine was cold, the oil performed at it's thinnest calibration and it went up from there to the operating temperature.
