I have just been reading the fuel gauge calibration notes in the recent MGB newsletter. So it got me thinking. I started typing the following tips up for the Safety Fast! Tech Tips page, and then realised that they might be more suited to the MGB Register newsletter.
Please note that if you are not technically qualified you should let a properly trained technician or electrician do these modifications for you. I have no mechanical ability at all, so appointed myself parts and catering manager!
1. MGBs were designed to run on 100 octane petrol. Period manuals from BMC/Leyland make this clear. So, I always run my Bs (and my modern car) on Shell V Power and I add Miller’s VSP to further boost the octane rating as well as provide protection against Ethanol. They run much better as a result. I always try to stick to one brand and I try not to use supermarket petrol whatever its octane. I have had totally contrary advice about this from Henry Cole who, years ago, was the Register Scribe, ex Esso man, who swears by Tesco Momentum fuel as it has no additives and is, therefore, closer in character to what we had to use in the far-off, halcyon days when our cars were young and we all had more hair!!….just saying…that’ll put the cat among the pigeons.
2. If the oil pressure takes a time to rise on a three-bearing engine when you start it then just turn the engine over a few times without pulling out the choke until you see the pressure needle rising up. Mine always takes a time to rise but it doesn’t seem to have done any damage over 20-plus years.
