> [@spanks"](#): > > you dont need us premium you say??? i lose nearly 200 km per tank running regular gas Now that is bullshit. It’s all in how you drive. KA’s do NOT need premium. Read your owners manual closely. It is recommended but not mandatory. Also, periodically…use Shell, Sunoco or Pioneer. NO other gas stations. ---

wow, you guys get crap gas mileage on your S13’s… I usually get 480-500 per tank (~50L each fill up) for mixed city/highway driving. For driving only on the highway I usually get 620-650km/tank (for about 50L of gas). That’s ~10.5L/100km for city/highway and ~8L/100km for highway only for my S14. Nissan’s figures for the S14 are 9L/100km for highway driving and 12.3L/100km for just city driving. For the S13’s you should get about 9.4L/100km highway and 13L/100km city. If you have anything above or below those figures you must check your car… i.e. O2 sensor, fuel filter, spark plugs, cat, coolant temp. sensor, knock sensor etc… Most of the time doing your spark plugs, checking timing and replacing the O2 sensor gets you better gas mileage. ---

^ most likely moisture man, nothing bad. a full tune up would be nice, also you can switch to synthetic, trust me, it’ll save you a bit on gas and also protect your car better too! ---

^^^ don’t switch to synthetic it’s a ka plus if the engine wasn’t using synthetic from the start it’ll just cause more problems. if it ain’t broke don’t fix it! keyword it’s a ka! ---

not true, don’t know bout high mileage ones tho since I made the switch at \<150,000km. But if your engine had problems to begin with that were hidden, that might explain it lol. but I couldn’t be better from regular oil to Royal Purple!🙂 ---

for better mileage use gasoline without alcohol. Alcohol burns slower than gas, and therefore does not get a complete burn in the combustion chamber, wasting fuel. It may take a few tanks to notice a difference when you switch. Good mileage is all about resistance. Use synthetic motor oil to reduce friction on cylinders, clean air filter, proper tire pressure. If you just brought it out of storage you might have a caliper sticking a bit cause friction on the rotor. Use low resistance spark plugs and wires. Man there are tonnes of thing that could be causing bad gas mileage.
