The parts did not change on the angled engines, but the valve
springs went from duals to singles.
I cant help with determining whether your "95 or 98" gas will work
in any engine, because these numbers are well outside what
would be considered normal ocatne ratings for street cars.
Im pretty sure that the specs for what the octane # means in europe
is different than what it means here in the states.
87 octane is a lower grade, but I've seen gas as low as 85 for sale
in other areas. This gas is suitible for most grocerie getters,
provided
they dont pink on it.
92 octane is "super unleaded", and is sometimes available
in 93.
Any rating greater than 93 would fall under the "race fuel" category.
Union Petrochemical sells 100 octane unleaded racing fuel at a few of
thier gas stations, and up to 114 octane racing "leaded" fuel is
available at the race track.
When I hear Europeans talk of 5 star petrol and "99",
I have to wonder what exactly that means.
