Rover 200 & 400 Owners Club

It will be E5 97 Ron for my 214 si 1990

I have always run my 216 Cabbie on 95 octane (E10) but, following the debate on the forum, I filled her up with 97 octane (E5) yesterday and what a difference that made! It’s like having a new woman (oops! I will have the politically correct forum after me for that remark) but she runs so much smoother with the different fuel. Ok, so it’s slightly more expensive initially, but with low annual mileage it isn’t going to break the bank.
And this lovely sunshine is just the excuse I need to stretch her legs. Vroom, vroom - I’m off!

But from September onwards it will be 97 or 98 as that doesn't have silly ethanol

I have been thinking about the change to unleaded, I have 1995 416 SLi its the one with a Honda Engine, the original instruction manual says it can run on 91 Ron Octane or higher so does that mean the change to E10 unleaded won't affect it and my 416 will be ok?

The octane number in this instance isn’t so relevant-it’s the effect of the larger ethanol concentration on the various seals & pipes within the fuel system.

Honda's guidance says that all vehicles with PGM-FI, which includes the D-series fitted to R8, is E10 compatible.

Land Rover's guidance is that all K-series, 4- & 6-cylinders, produced after 1996 are also E10 compatible.

Unless there's something else we don't know about it's likely that all K-series in R8 are OK too but we can't yet confirm this. The same uncertainty exists for M- & T-series...

Transition now taking place; yesterday one Esso filling station in Lichfield had E10 but another Esso one in Stafford had E5.

Parked next to an early 416GSi with club sticker @ Stafford rail station!

They're still out there

I am totally confused. I’ve been using normal unleaded in my 1992 214 engine. Does the change in the petrol mean I should now switch to the super unleaded? Sorry but I don’t find it easy to follow this debate
What does E5 and E10 refer to. Is the E5 the equivalent of super unleaded . And what’s the risk to the fuel lines?

E5 is 5% Ethanol and E10 is 10% Ethanol, E5 should be around for some time yet but perhaps in Super Unleaded form. I would stick to E5 until we know more as the Government website doesnt say anything about Rovers due to Rover being extinct.

Unless someone knows better?
