Your girly friend is correct. If it does not run properly on 87 octane
gas, you need a tune up or some repairs. All gas must contain detergents
to keep the injectors clean. The high octane gas is mainly used in
vehicles that have high compression, typically above 9.5:1, to prevent
detonation. The rest is marketing hype.
As for Lucas products, why not go use a good synthetic lube instead of
adding crutches to your petroleum oils? Additives of any make will not
change the basic problems with the dino oils. Short lives, poor high
temperature performance, poor low temperature performance, poor shear
stability, cheap additives in the base oil. See previous emails on this
discussion.
