We live in Germany and I have some difficulties in relation to several specifications and needed fluids. I would like to make several Troubleshootings Prior starting the Project and there begins possible mistakes which I would like to prevent, under and with your experts help. Which engine oil do you use. I think it should be 20W50, but can you recommend a brand/make? Do I will need any additives. Which gearbox oil do you use? Which spec? I have the 4 Speed gearbox installed. Please advise also suitable make. Further, I would like to change the oil from the diff. Which one you recomend? Any spec and make/brand? I have plenty gallons of D.O.T. 4 brake fluid, can I use it for the Healey or should I use D.O.T 3 brake fluid? Last but not least, We just are able to use the 98 octane gasoline. Do I Need to use any additive in the tank for the fuel supply? Many Thanks in advance, Eurico |

Welcome to the message board Eurico. The engine oil should be 20w50 with the zinc/ phosphorus, ZDDP for older engines. I use Valvoline VR1 but don't know if it's available in Europe. 4 stroke motorcycle oil will also work. The 4 speed gearbox also uses the 20w50 engine oil or synthetic Redline brand MTL. Other brands will work fine. The diff uses 75w90 hypoid gear oil. Synthetic is ok. I have had good luck with Dot 4 synthetic brake fluid. The pent roof 4 valve head is not sensitive to octane. You should not need any fuel additive. This engine can easily run 11:1 compression on pump gas. Cheers, Kurt |

In addition to our "moderator's" recommendations, I woujld also add (4 speed only) Dow CVorning "M" Gear guard to the transmission and differential. 10% is what's called for which is about 5-6 ounces for the Tm. and 2-3 for the diff. |

Thanks a lot. Do you use also Valvoline VR1 engine oil? I was today at our local dealer for us Parts where I usually by the parts for my Chevy. And they like me never had heared about 20w50 engine oil in the TM. |

I use whatever high grade is available; sorry, can't help you much with that but I don't think it will greatly affect the engine |

Thanks, I have no doubt that it will affect the engine. I just wanted to be sure in regards to the TM. And the V1 is hard to get where I live. How ever, it will work. 😃 |
