Oil exiting the crankcase breather

It costs £150 to fill up my XJ with super unleaded.

I have never filled up the S Type to capacity but working on an average price of £1.25 per litre for Unleaded X 14 gallons X 4.55 that means about £79.60 to fill to the brim and that should get me 252 miles at 18 to the gallon. In the UK that's like driving halfway to the moon. When I go to Coventry in June I will be able to test out my theory because that's 200 miles each way for me.

I reckon you'll have to fill up before you get to Coventry to be on the safe side as you will consume more gas on the motorways with the higher speed. I only use super unleaded and that costs £1.32 at my local BP station. In the "olden days" if you did a constant 100 mph you could see the fuel guage dropping before your eyes.

We will see in June how far I get. I have seen the gauge dropping on a trip down the motorway. With the one 7 gallon tank on the gauge at a time, it is more obvious than having one gauge on a 14 gallon tank.

I have always used 87 octane Regular Unleaded, in both cars, no pinging.

gas is $2.29 - $2.49 over here..More expensive in California and other Western states.

Our standard 93 octane contains 5% ethanol - not good for our cars fuel system and lower mpg.

I use super unleaded as standard unleaded gives my engine the runs. Sorry run on as when I rebuilt my engine I put the higher ratio 9:1 pistons in after the rebore. I could switch the ignition off get out of the car, open the boot and set my chairs up before the engine would eventually stop chugging and die on the regular stuff. Super unleaded stopped that for me.

Our Sasol fuel that is supplied to the entire highveld region can contain up to 12% heavy alcohols, that come off of their coal gasification process, can be a menace. I bought milky clear nylon fuel line from the US as being "the right stuff" & suitable for E85 & California etc. ethanol areas. Well the Sasol fuel destroyed it in about a week. So I threw authenticity out of the window & went for practicality. Cursed stuff gave me a real headache.
