What's the view on using toyota motor, this stuff they recommend for petrol & diesels. 20W/50 SJ/CF

Seems like a "she'll be right mate" put it in everything oil.

Hi Phil I tend to think 20w 50 is too thick for a diesel, the most common spec oil for diesels is CF4 15w40 The best value oil filter for 1HZ is Motorcraft AFL60 available from Ford dealers! This is an Australian made filter and should retail for about $22.

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

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,

Been using Shell Rimula X 15W/40 in Toyota 'cruisers and hilux's for nearly 30 years, and have never had any engine, or glazing problems. This is for both work, and private vehicles, used on stations in Qld and NT.
And you can get it anywhere. Hooroo...

Hi Phil. You;r theory on thicker oil could be correct, I have experienced this myself in the past. Indirect injection diesels thicken the oil due to soot contamination that is why you change every 5000k ,starting off with a thicker oil in the sump will compound the problem. The trend these days is toward low viscosity oils even in petrols,some manufacturers recomending 0w30 or 5w30 !

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.
Regards to all
Donald

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.

Hi Andrew

I'm not running a turbo, I looked in the owners manual some time ago and 20/50 appeared suitable for my location which is mostly around
the north central to south east Vic area. It gets oil and filter every 5,000.

I'm still tossing up whether or not to change to 15/40, most people
think that's the way to go.

Phil

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.

Regards
