SPC 98- Bad power, bad consumption, loud engine
Shell 98 - Decent power, best consumption amount all, smooth quiet engine
Shell V Power - Very good power, O.K consumption, smooth but slightly louder engine
ESSO 8000 - Good power, good consumption, smooth engine
Been using ESSO 8000 'cause of the results of the fuel and the discounts i get, it's the best balance to me. If Shell had very good credit card discounts like ESSO i would be pumping Shell 98
