Hi Huddie and welcome,
In the opinion of most the oiler is not well regarded, including the main dealer where i brought my +8, he advised against it and regular greasing.
The pillar suspension system is packed with grease and the stub axles slide up and down on bronze bushes, the pillar restrained by the top and bottom springs. If you use the oiler on a car with it then it will thin and wash the grease away and wear rate on the pillar and brass bushes will reduce. (Especially with hot engine oil) Also if over used there is risk of oil seepage getting on brakes.
A lot of MOG owners disconnect the oiler and then use a grease gun at the top and bottom of the pillars (remember to clean away an excess grease after doing so around the stub axle after greasing). This is tedious and messy, requiring front wheel removal and jacking up the car. If you look in Miscellany there is a remote grease nipple kit available. You replace the top and bottom nipples with the ones supplied and from these run pipes (supplied) to a metal block you fix on the inside wing, this has grease nipples. Now greasing is easy, open bonnet one side and pump grease check now and then for grease coming from stub axle, clean off and do other side. Much easier, I fitted this before it was available as a kit and is well worth the cost, and not so dirty hands.
Enjoy your MOG
