But I think you missed mine.. there is also nothing about the 98 spec that supports your claim.. according to the fuel standards, it can be identical to 95, just very slightly higher octane number. But the ulp vs pulp fuel regulations go show 95 (or 98), is not just 91 with some additives. any claim of ‘refined by the better refineries’ or ‘higher quality fuel’ is just hearsay. I have never seen anything to back up such claims other than ‘my mate used to work for a fuel station’, or ‘drove a fuel delivery truck’, or ‘my mechanic says’.. the actual energy densities do slightly vary between the 3 grades of fuel, but the difference is very minor. That said, I am very happy to be proven wrong if anyone has some hard evidence.. -
Hey guys I’m chasing a Rb20det complete or bare block need a good running engine as mine has low comp -
You're making my point for me. 95 is not "premium". It is a "slightly higher octane" version of the basic 91 product. The premium product that they want people to buy (for all the venal corporate reasons of making more profit, and all the possibly specious reasons of it being a "better" fuel with nicer additive packages) is the 98 octane stuff. 95 is the classic middle child. No-one wants it. No-one cares about it. It is just there, occupying a space in the product hierarchy. -
98 and 95 have to meet the same national fuel standards beside the actual RON. 91 has lower standards (which are quite poor really), so 95 is certainly not 91 with some octane booster. It would be an easier argument to claim 98 is just 95 with some octane boosters. Also RON doesn't specify 'quality' in any sense, only the octane number. Anything different retailers decide or not decide to add to their 95 or 98 is arbitrary and not defined by the RON figure.
