so i haven't really been able to find much on what fuel an EA-71 likes to run on best, seems that a RON of 100 leaded fuel was the default for the EA-71 back in the 70's?
seems that the closest we can get to today is an octane rating of 93 at a typical gas station and some fake lead additive for our vehicles at the autoparts store, does the engine really need the additive? what is in it anyways because i doubt its actually lead with all these regulations today. i think i recall reading in the original water damaged owners manual in my vehicle that it prefers an octane of 90 or higher?
being a NON-CATALYTIC vehicle as it says on the door tag means it would prefer Leaded Gas, right? and that the engine was designed for Leaded fuel, hence the name EA-71 for 1971 designed engine.
any opinions? not sure on my facts.
