Cenex gasoline.
Every grade TOP TIER.
Every grade of gasoline at Golden Ox Hays, Golden Ox Wilson and Southside Convenience is Cenex TOP TIER detergent gas. We also sell diesel for pickups, farms and big rigs, and DEF at both truck stops.
Pick your grade
Not sure which one? Check your owner's manual or the label inside your fuel door. Higher octane only helps if your engine calls for it.
Unleaded 87
Everyday regular for most cars, trucks and SUVs. Safe for any engine that takes regular unleaded.
Unleaded 88
More octane, usually for less. Unleaded 88 is 85% gasoline mixed with 15% ethanol, a renewable fuel made from corn grown right here in the Midwest. You'll find it at all three CTA fuel stations. If your car, pickup or SUV is a 2001 or newer, or it's a flex-fuel vehicle, the EPA says it's good to go. Please don't use it in motorcycles, boats, small engines, off-road vehicles or heavy-duty engines.
Plus
A step up in octane for vehicles that recommend midgrade, blended at the pump from our regular and premium.
Super 91
Premium unleaded for performance and luxury engines that require or recommend 91 octane. At Golden Ox Wilson and Southside it's ethanol-free (E0), ideal for boats, mowers, chainsaws, motorcycles and classic cars. At Golden Ox Hays, Super 91 is E10 (up to 10% ethanol).
E30 Flex Fuel
A higher ethanol blend for flex-fuel vehicles only. Look for a yellow gas cap or a "Flex Fuel" or "FFV" badge on your vehicle.
Cleaner engine. Same price.
TOP TIER is standard in every grade of Cenex gasoline, so you never pay extra for it. According to Cenex, it is certified in four tests to exceed EPA detergent requirements and is recommended by 7 of the top 10 automakers.
Built for the long haul
#2 Diesel
Clear on-road diesel for pickups, cars and work trucks at our auto pumps. In the winter months we switch to winterized diesel, blended to resist gelling and keep your filters flowing in Kansas cold.
High-flow truck lanes
Dedicated high-flow diesel lanes so big rigs fill up fast and get back on I-70.
Off-road diesel
Dyed diesel for farm equipment, generators and other off-road machinery. It's illegal to use dyed diesel in vehicles driven on public roads.
Diesel exhaust fluid
DEF at the pump for diesel engines with SCR emissions systems, so you don't have to haul jugs.
