Cheers mga bro. I am just new here hope I am welcome. I just bought a used ford lynx gsi recently. the seller advice me to use petron blaze only for the good engine performance but the problem is to have that gas is too hard here in my place I should travel 60 kms just to have it. Heck, If I only knew that it would affect the engine by using gas with lower octane rating I will not buy this car. The Performance is good and I am satisfied but to have that type of gas is the major concern. Can you experts advice me what should I do? is it an engine problem or something? I never tried vortex gold which have 95 octane rating but I dont want to take a risk, or is it really a risk? Please email me at malvintenorio*yahoo.com.ph if its not too much to ask from you please help me with this concerns. I will really appreciate it. You guys are really helpful. Cheers
