Oils ani't oils Are they?

Gunna do the fuel filter??
Been using the Valvoline stuff for a long time. Obviously there's better (& worser) stuff out there?? So long as it meets or exceeds the API rating...
Probably out of your expertise- but when where the injectors last overhauled??

Dont forget the diff oils, tranfer case, gear box. At least you will no they have been changed and all is new wether they need it or not. Check out the diff breathers as well. Intending to do a few water crossings ?? I would be extending the breathers nice and high so they suck in any water into the diffs. Easy job to do. Dont forget the clutch and brake master cylinders as well. Might be worth giving a flush through, possibly power steer as wellRegards Steve M

Ian,

Don't claim to be an expert on oils but can say I was involved in the oil industry for 32 yrs. Certainly there are oils and oils. There are standards and specifications for each API rating and say on a scale of 1 to 10 there some oils will just reach the bottom of the scale while others are nearer to the top mark. The base oils used may all come from the same source refinery and the final products may be blended and packaged in the same plant however it is the 'additive package' which is added to the base oil which makes the difference on the rating scale. Some use a cheaper 'package' which gives an advantage in the market while others choose to build the final product on quality. Which is right?

To give an example. If I graduate from Uni as an engineer with Hons and my friend graduates with a basic level 5. We are both engineers and we can both do the job. Only time will tell and it is not possible to predetermine which will be the best in the long term.

When I bought my Tojo TD 4.2 I contacted one of my old associates who specialised in lubricants for some 45 years and he went right up the line to Japan only to come back with his own assessment and recommendation.

The biggest issue with any diesel is keeping the operationally produced contaminents at the lowest level and since the oil in the sump is where all the carbon and crud ends up the best method of contaiment can be achieved in my book by using good quality filters together with an oil that meets the set standard and then replacing both often. A point often lost with diesels is the air cleaner element. It may look clean but if you are running in dusty conditions a change could be a good move. Just remember if you use a blast of air to back clear the filter it is also very possible that you are decreasing the efficiency of the filter by enlargeing the entrapment structure which will subsequently allow more dust to enter the system.

Just my opinion. Incidently you will note I am not pushing any brand as my association has ended.

Ask the previous owner what oils he has been using & stick to that!

hi noldi

G'day Noldi,
Probably telling you nothing new but when you refill your cooling system make sure you refill it with de-mineralised water from the bottles. Saves from mineral deposits building up in your cooling system.

Cheers, Heefers

G'day Ian,

Most important advise I was given with diesel engines was when the kilometres got up over the 100,000 mark, try to avoid changing the brand of oil that is used. Apparently different diesel oils have cleaning agents in them and changing the brand can cause the lubricant to strip the previous lubricant from the walls of cylinders and bearings prior to the new oil taking over. During this period, damage could occur. I am no expert, but I have followed this advise and have 322,000 on the motor and it is still going strong.
Good luck,

Lindsay

My mechanic has also advised me to keep the same type of oil. I do the 5000 km changes and I get him to do the 10000 km changes. I now buy my oil from him for the ones I do to keep the same type of oil, he sells it to me a a price comparable to what I can find anywhere else so thats okay. Seems to make some sense I guess and if it costs you nought extra to keep the same type, why not. For the record its Fuchs oil that I use now.

Is it a manual? Hope it doesnt have a dual mass flywheel !...silverback
