WBX Head Problems

1
Before 95 octane fuel became readily available T25 Transporters were having trouble with cracked heads. The lower octane fuel burns hotter which causes heat cracks in the heads.

Many years ago burnt valves were common in air-cooled Beetles and Kombis when people used standard fuel instead of super. False economy!

Over the year, how much extra in fuel costs would there be using 95?

Phill,

Thanks for the elaboration.

Joachim,

This harks back to the fuel question that you asked me when you were
in West Australia. The increase in percieved performance is simply
a function of the greater calorific value of the 95 fuel. Phill has
added very interesting information about the history of head
cracking. As Phill says, it is a comparison between the extra cost
of the 95 and the cost of cracked heads. In view of this, I will be
happy to pay the difference to use 95.

Les and Phill,

* That's what I thought when you started the topic #smile# *

The increase in percieved performance is simply
a function of the greater calorific value of the 95 fuel. Phill has
added very interesting information about the history of head
cracking. As Phill says, it is a comparison between the extra cost

* Your both right on this one. Not only the cost of cracked heads, but also
time and effort to get things going again... *
