Thread: NSW & Vic Petrol

BMPF BMPF BMPF helloo, is this thing on?

My 2a lives on NSW unleaded, and has done since leaded petrol stopped, and is in practically daily use. The only fuel component I have replaced in that time is the fuel filter (non-standard), and it continues to run well.

I conclude that NSW petrol (which is likely to contain ethanol - mandated 10% average, but this does not mean all fuel has that amount - some may have more) is not doing any harm. As far as I know, Victorian petrol is the same as NSW.

Awesome. Thanks John

Have you done anything to the head or just left it until she needs new valve seats?

Still on their current website:
Fuel - RACV

They have published:

In NSW the government have mandated up to 10% ethanol in ULP.
In Victoria, as far as I am aware, no such mandate exists. There would be an uproar if they introduced it.

No. Overseas experience (e.g. Canada) suggests that valve seat recession in this engine is unlikely unless used extensively at high power and high rpm, for example in prolonged freeway driving. I suspect this may be because of good design of valve cooling and the fact that these engines are relatively low compression. If the power is increased substantially (which is relatively easy), I expect the situation could be a bit different.

Valve seat recession is easily spotted when you adjust (or at least check) the tappets, probably a good idea at every or every second service. And think about getting the head overhauled and steel seats installed if overhauling the head.

(For completeness, note that the overhead inlet side exhaust engines fitted to Series 1 and Series 2a/3 sixes already have these)

Thanks John. It fits in with my MGB experience where you didn't worry about it unless you found yourself rebuilding the head. Of course, some people get hysterical about it.

I read the question to be about the effects of ethanol on fuel systems not ULP on valve seats.
AFAIK ethanol can affect certain rubber and plastic parts in fuel systems causing degradation and possible failure of seals, diaphrams etc.
If you google E10 vehicle suitablility LR series vehicles are definitely not suitable for E10.
I do know that ULP without ethanol is still available in NSW after they tried changing to all E10 in 2013(?) and reverted back to straight ULP and an option of E10 after a public outcry.
Not sure about SA but things like chain saws, older mowers etc definitely don't like ethanol so I would imagine that staight ULP is still availabvle there as well.
