  • Amsoil diesel oil

    Hi Has anyone considered using Amsoil synthetic oils ? All I know it's pretty pricey but when you consider the time frame and kilometers between oil and filter changes it maybe worth it ,Maybe ????????

    You'd be better off using a cheaper oil like Delvac or Delo and changing it every 5000km to get the soot and unburnt fuel out of the engine more often.

      Re: Amsoil diesel oil

      also think about getting an oil you can get relativly easily when travelling...

      personally having worked for big oil testing samples from all fields automotive mining/heavy industry etc and running my own workshops i wouldnt sway from the likes of

      Mobil
      Castrol/BP
      Caltex

      Support for the product nationally able to source at thousand of outlets across australia

      For 10k oil service intervals all of these companies make some excellent oils that would handle any conditions you could throw at them, all have semi and full synthetics of varying degrees and ranges that would far exceed the requirements set by Toyota for the oil specs in any of their motors. Sure if your running a performance motor at much higher strain levels with massivly increased internal shear rates then you might need a specialised product.

      Personally though I wouldnt touch one brand in particular 'you know what i mean'

          Dear "Large a a Prado",
          Its great to hear from an oil tester, and good advice re: oils, but when you look at Mobil, Castrol or caltex oils there is still some choice within the range....so, please, are you able to be a bit more specific....what do you use in your Prado and why?

            Oh, and we "know what you mean".....but honestly, in your opinion, why? Has your experience been that this oil is just not standing up in tests??

              Hi All,

              I have just graduated from the 120 Series forum to the 150 Series forum and I am finding it just as interesting. I have to say I do miss my 2005 Petrol 120 Grande but the 2011 150 Series Kakadu Diesel is an impressive machine, on the subject of oil, the information contained in T's manual for the 150 Series petrol engine is very straight forward, an SL or SM service classification oil (both are current service classifications) at the viscosity appropriate for your operating temperature range. In the 120 Series for me it was Castrol 5w-30 and the engine was in very very good shape when I sold is at near 200,000 klms.

              The diesel I don't beleive is so straight forward, from page 599 T recommend that a API CF-4 oil and even CE or CD service classification may be used. What the I had to read it 3 or 4 times to ensure I had read it correctly. The CD & CE service classifications were obsoleted years ago as CD & CE oils where designed for high sulphur fuels used from the mid 50's to the early 80's on engine with no emmission or little control systems, our fuel and engines are very different now. No way I am using a API CD or CE oil!! So what about API CF-4 this also is an obsolete service classification and API are at now classification CJ-4.

              So whats is going on? Why have T specified obsolete oil service classification oil? The D4D is a modern engine using low sulphur fuel which is turbo charged and emmission controlled.

              So what is the difference between CF-4 and CJ-4, lots

              Based on API, I understand that API CF-4 was obsoleted in 1995 (16 years ago) because it did not preform well with low Sulphur fuel. It also contributed to airbourne particulate (smog) and was not efficiently processed by the emmission control system on the newer engines.

              So what about CJ-4, well from API's website

              For high-speed four-stroke cycle diesel engines designed to meet 2010 model year on-highway and Tier 4
              nonroad exhaust emission standards as well as for previous model year diesel engines. These oils are
              formulated for use in all applications with diesel fuels ranging in sulfur content up to 500 ppm (0.05% by
              weight). However, the use of these oils with greater than 15 ppm (0.0015% by weight) sulfur fuel may impact
              exhaust aftertreatment system durability and/or drain interval. CJ-4 oils are especially effective at sustaining
              emission control system durability where particulate filters and other advanced aftertreatment systems are
              used. Optimum protection is provided for control of catalyst poisoning, particulate filter blocking, engine
              wear, piston deposits, low- and high-temperature stability, soot handling properties, oxidative thickening,
              foaming, and viscosity loss due to shear. API CJ-4 oils exceed the performance criteria of API CI-4 with CI-4
              PLUS, CI-4, CH-4, CG-4 and CF-4 and can effectively lubricate engines calling for those API Service Categories.
              When using CJ-4 oil with higher than 15 ppm sulfur fuel, consult the engine manufacturer for service interval.

              As we good folk in Australia use 10ppm sulphur fuel since Jan 2009, again What The CJ-4 seems to be the correct oil for the D4D.

              So I didn't get why T did not specify in the manual API CF-4 or better for the D4d until i rang T, and yep I got the usual run around and this old gem "the manual is printed for English Righthand Drive Vehicles around the world and that some information relating to the vehicle is general in nature". In the end I had to give up on getting an answer as these guys are expert stone wallers, my pathetic parting shoot was to reminding them that my vehicle is a retail $105,000 vehicle and the best they can do is give us a genreal manual.

              I would love to hear from the forum on what oil you are using, but I am not using and osbsolete service classification oil in a 2011 turbo charged emmission controlled D4D.

                Hi Steve

                There are probably a few answers to your questions.

                You are probably being stonewalled because the service people dont know the answer and simply do what they are told by the engineers. They should just say "no idea". The D4D is a reliable engine and is used in heaps of Toyotas - hilux, prado, hiace etc and there is no identified issue with them say like a 3l Patrol. If they do get failures then the engineers should be able to identify if its an oil issue or not. Despite the issues you have raised I think I would still go with what toyota recommends simply because it is in their best interests financially, and through reputation, to not have engine failures and this is bread and butter stuff for the engineers. One good thing about Toyota is they hang on to engines for a looong time so any issues are well known.

                If you get Toyota to do your servicing and then take out the extended warranty it will be a looooong time before its an issue and if the engine fails after this time then you have a case with small claims.

                    Hi Steve,

                    To confuse matters more, if you go to your friendly T dealer to buy some diesel engine oil, they have a Toyota branded diesel engine oil that is 15W-40, CH-4 spec.

                    I had to do an oil change recently and I do appreciate that modern diesel and petrol engines now use lower viscosity oils, presumably to achieve better fuel economy and yet have just as good engine protection due to better oil formulation. But a part of my "old school" thinking is that the "heavier" viscosity oils will provide more protection under high load conditions.

                    Anyway, armed with this confusion I visited Repco, to look for an oil that I can find off the shelves, readily available anywhere in Australia, that i can use to do an incremental oil change at 5000 km interval. Why do additional oil changes, when the dealer is recommending 10,000 km intervals, I hear people ask? Again my "old school" thinking is that the less soot there is in the diesel oil, the better it will be for the engine, regardless of whether the oil is 100% fully synthetic or semi synthetic.

                    When I got to Repco, I found Castrol Magnatec 10W-40, which is a CF spec oil. Sounds about right - thinner, but not too thin than the traditional oils, semi synthetic, and formulated for a diesel engine, available everywhere and even Gilly (Adam Gilchrist) and the Indian Cricket team endorse the Magnatec product. But I baulked at the $45 for 5 litres price.

                    Off to T dealership, and they have a 15w-40, CH-4 spec "diesel" oil. Price was $42 for 5 litres, so it was cheaper, had a slightly newer oil spec and most of all, has the Toyota endorsement. After all, Toyota can't possibly void my warrant for using Toyota diesel oil!

                    So that's what I'm using now. Toyota oil, and I hope that at 5000 km oil change intervals, it's not really going to matter what the spec is not the same as the antiquated oil specs found in the user manual. I believe that those specs are a "lowest common denominator" for markets where the Prado diesel may be sold into which have not made the switch to ULSD diesel.

                    I am guessing that in countries where there is high sulfur diesel, CD spec engine oils can still be found. Next time I visit a 3rd world country, I'll drop into the auto parts store (if I can find one) to have a look see.

                    So has this helped you? Possibly not, but I too went through the same vexing thoughts as you when I tried to find the right engine oil for my Toyo offroader.

                      If you go to your friendly Toyota dealer to buy "Toyota Diesel Engine Oil", they will sell you CH-4 15W-40 over the counter. Is CH-4 oil suitable for the D4D?

                      Here is a picture of the Toyota oil bottle:
