Below are some feedback from our customers. 

           From T.J Automotive & Motorcycle Performance

Recently I travelled from
Sydney to Darwin in the Northern Territory…Over a period of ten days I travelled 8500km towing a 3.5 ton Race Trailer. During trips of this distance I would expect to use 1.5 to 2 litres of oil. Before commencing the trip I serviced the vehicle with 2 litres of Donald Oil 3in1 additive in the engine also Diff &High Speed Manual Gearbox were treated with Donald Oil. At the conclusion of the trip no oil was burnt whatsoever.  As a qualified mechanic and dealing automotive oils for many years I find the performance of Donald Oil exceptional and therefore I highly recommend this product.

Just a little note of thanks for the service you have given us for the last 13 years. Over that time we must have used hundreds of litres of your Donald Gold 3in1. We have found it far superior to many factory recommended products. Especially for the swivel balls on Rangerovers . Discoverys and Defenders. Your product can be used to stop or slow down minor leaks of the swivel ball seal saving time and money on changing the seal. We have also found it very useful for older motors extending their service life, reducing emissions and oil consumption.
