I'm with YF on this, I have been using 2 stroke oil since the car was new and have been pleased with the mpg and general performance delivered. If I could get it, I would go further and use bio as I used to in my defender at a ratio of 90%, but the supplier has been muzzled by the incompetence of local government, one department giving him approval to produce and market the stuff, and another prohibiting him!

good morning YF and ou toppie! I have been following the deliberations in this thread for some time now. I am writing technical articles and comments in SA for the LROC and the MBCSA. I would like to comment on the practice of adding 2-stroke oil to diesel fuel and also to the debate of 500ppm versus 50ppm diesel. First the diesel question: Apart from the Sasol 50ppm diesel, all the other 50ppm brands are imported into SA. Until a few years ago we didn't have a legal stipulation to disclose the sulphur content of diesel. It was quite common for diesel in SA to have a content of up to 3000ppm. From those days stems the practice to half the engine oil change frequencies. For those of you posting negative comments on this thread about why they don't believe and/or support YF's tips on using 2sO (2-stroke oil), there is a very quick and efficient way to scientifically proof the devastating effectiveness of using 2sO. Take an oil sample and send it to Wearcheck for analysis. Then do an oil change and immediately start using 2sO together with 50ppm diesel. As a first dosis add 1litre to every 100litres of diesel only for the first tank. from there on go with YF's suggestion of the 1:200 dosis. Drive like that for 5000km and take a further oil analysis. If the oil is fit for further use, repeat at 7500km and at 10000km. You will now have a benchmark and adjust your oil change frequencies to suit. I change at 7500km because I drive an old type 300Tdi engine. Specific to SA conditions the following will happen. During the first 1 or two tanks you will feel at times a vibration coming from the engine coupled with some scary blue smoke belching out from the back. This is quite normal and is a sign and proof that the carbon deposits are being burnt off. You will be amazed how much smoother the engine will perform after about 5-10 tanks. Yamaha Fan must be congratulated for her willingness to share her insights with us.

Hi Dave We have been using 2sO here in SA in various car clubs for years now and because of our country specific problems (dirty diesel, diesel stretched with paraffine etc) we have no other alternative. One of the rice bowl manufacturers, selling bakkies into the SA market for longer than I can remember, have a serious problem at present, with their CRD engines going through injectors at a rate of approx. every 80'000km. This is as a direct result of diesel being sold with insufficient lubricity. Land Rover are loosing CRD pumps at an alarming rate on their Freelander and Disco3 and 4 models as well as on the RR diesels. But these failures only affect owners of vehicles who refuse or are not aware of the benefist of 1:200 ratio of 2sO mixed in with the diesel. So the advise that YF has been giving to this forum since 2007 is of immense value. But there will always be people who dispute every positive new development, for whatever reason. Dave I would suggest that you take off your myopic glasses and start seeing the benfits.

This notion of possible harm to engines has come up a few times now. I may be wrong, but it would seem extraordinarily unlikely that the addition of such a tiny quantity (1 part in 200) of something which is not that different from diesel itself could actually do any harm. It's worth remembering that diesel engines are designed to cope with a very wide variety of fuels around the world - it's not as if it has to be a very precise formulation. |

Ou Toppie in SA I use the Sasol 50ppm and the Sasol Corwa120 2sO. Sasol is in the process of repackaging their oils and the new canisters (currently only in 200ml) very clearly state JASO-FC compliant. Sasol Corwa is a low ash formula suitable for premix and oil injection. On your Freelander use 1 200ml bottle per fillup. That will give excellent protection With kind regards DiscoGeorge 1998 Disco1 ES 300Tdi with twin TrueTracs 2005 Disco3 TDV6 S And some more serious stuff |

Hi guys the Fischer Tropsch method was developed in Germany after 1925 and entailed the fuel from coal process. This was adopted by Sasol in South Africa and for the last 30 odd years has been one of the main fuel suppliers in SA. Sasol runs two fuel from coal plants in Sasolburg near Vereeniging and in Secunda near Witbank/Middelburg. The diesel extracted by Sasol is the cleanest diesel available in SA and also the one with the highest cetane rating at 47 (in Germany 52-23). For the MB, BMW and VW CRD engines this is still to low and here in SA we apply the 2sO addition for two reasons. To add lubricity and to up the cetane rating of the diesel. It works like a bomb.
