For most of racing history, getting the right fuel meant knowing someone at the track, having a relationship with a local supplier, or showing up early enough to grab what was available before it sold out. That has changed significantly. The full range of race fuel is now available online, shipped directly to your door, and ordering the right product has become more straightforward than most racers expect.
The part that trips people up is not the purchasing. It is making sure the fuel in the cart is actually the right fuel for the engine before checkout. Ordering the wrong octane, the wrong oxygenation level, or the wrong leaded versus unleaded formulation does not just waste money. In the worst case it puts the wrong fuel in a precisely tuned engine. Getting that step right first makes everything else easy.
The most important thing to do before buying race fuel online is confirm which fuel your engine actually needs. Octane is the obvious starting point but it is not the only variable. Leaded versus unleaded matters for any engine with oxygen sensors or catalytic converters. Ethanol content affects tuning, fuel system compatibility, and storage behavior. Oxygenation level changes air to fuel ratio requirements. Racing discipline sometimes influences what a sanctioning body permits or requires.
If you are new to race fuel and still working out whether the jump from pump gas makes sense for your build, this breakdown from Grassroots Motorsports and Sunoco's technical team walks through the progression from pump premium to purpose-built race fuel in plain terms. For anyone who wants to understand what actually drives fuel selection before opening a shopping cart, the key factors to consider when choosing a race fuel covers the full decision tree of street versus race use, leaded versus unleaded, oxygenation, compression, and RPM range. And if octane itself is still a bit unclear, everything you need to know about octane for race engines goes deep on what the number actually means, how it is measured, and how it relates to the specific demands of your build across the full catalog from 94 to 118 octane.
Trying to sort through all of that from a product page is harder than it needs to be. The Sunoco Fuel Selector is built specifically to work through those variables before you buy. It asks about your minimum octane requirement, whether you need leaded or unleaded fuel, your ethanol preference, and your racing application, then returns a specific product recommendation rather than a list of options to figure out yourself. Running through it before opening a shopping cart is the difference between buying with confidence and hoping for the best.
Once you know what you need, Petroleum Service Company is the place to order it. PSC carries the full Sunoco race fuel lineup with direct-to-door shipping, available in multiple container sizes to match how much fuel you actually go through.
The product range covers the full octane spectrum from Sunoco Optima at 95 octane for powersports and storage applications all the way through SR18 at 118 octane for dedicated competition builds, with leaded, unleaded, and ethanol options across the range. Commonly ordered fuels include Standard 110, Supreme 112, and 260 GT at 100 octane, each available in 5-gallon pails and 54-gallon drums depending on volume needs.
PSC also organizes the catalog by category if you want to browse by type rather than by product name. Unleaded fuels, leaded fuels, oxygenated fuels, and alcohol-based fuels each have dedicated pages, and a fuels by octane rating page makes it easy to find options at a specific level if you already know what you need. For those who want a side-by-side overview of the Sunoco lineup before committing to a product, the Sunoco racing fuel reference page on PSC is a useful quick reference.
If you prefer to buy locally or pick up from a dealer rather than ship, the Sunoco Fuel Finder locates authorized dealers near you.
Yes, and this is one of the questions that comes up most often from first-time online buyers who assume hazmat regulations make home delivery impossible or complicated.
Race fuel is classified as a flammable liquid, which means it falls under hazmat shipping regulations and requires specific packaging, labeling, and carrier handling. Reputable online suppliers like PSC handle all of that on their end. The fuel arrives in DOT-approved containers through carriers equipped to handle hazmat shipments, and the process from the buyer's side is no different from ordering any other product.
The practical considerations are worth knowing: hazmat surcharges apply to fuel shipments and show up in the shipping cost at checkout rather than being buried in the product price. Lead times are typically slightly longer than standard ground shipping, which matters for race weekend planning. Ordering a week or more in advance rather than a few days out removes the risk of a delivery delay becoming a problem. PSC ships to home addresses, businesses, and shops, so the delivery destination does not affect whether the order can be fulfilled.
For very large orders, 54-gallon drums ship via LTL freight rather than parcel carriers. PSC provides freight shipping options at checkout, and for teams or shops buying at that volume the per-gallon cost reduction typically more than offsets the freight cost versus buying in pails.
Container size is worth thinking through before placing an order because it affects both cost and fuel freshness.
A 5-gallon pail is the right starting point for occasional racers, weekend events, or anyone running a single vehicle on a limited schedule. It keeps fuel fresh without the risk of a large quantity sitting for an extended period, and the per-gallon cost is manageable for low-volume use.
A 54-gallon drum makes sense for regular competitors, shops running multiple vehicles, or teams that go through fuel consistently enough that freshness is not a concern. The per-gallon cost is meaningfully lower at drum quantity, and having a full drum on hand eliminates the scramble to reorder before each event.
One thing worth factoring in: non-oxygenated race fuels like Supreme, Standard, and Optima hold well for two years or more in properly sealed containers, so buying in larger quantities is practical for fuels that will be used regularly over a season. Oxygenated and ethanol-containing fuels have shorter storage windows and are better matched to quantities you will use within a year.
Buying by octane number alone is the most common one. Octane is not the only specification that matters, and two fuels at the same octane level can have meaningfully different specific gravity, oxygenation, ethanol content, and burn speed. A 110 octane fuel that contains ethanol and a 110 octane non-oxygenated fuel behave differently in a carbureted engine tuned for one or the other. Using the Fuel Selector rather than filtering purely by octane avoids this.
Ignoring leaded versus unleaded is a related mistake that can cause immediate and expensive damage. Leaded fuel permanently destroys oxygen sensors and catalytic converters. Any modern fuel-injected vehicle or any engine with emissions equipment needs an unleaded fuel regardless of the octane level required. The Sunoco fuel catalog makes this distinction clear on every product page, but it is easy to miss when browsing quickly.
Not checking class rules before ordering catches people out more often than it should. Some racing series specify a particular fuel or maximum octane level. Showing up with the wrong fuel for tech inspection is a problem that a two-minute check of the rulebook would have prevented.
Ordering too close to race weekend is a timing issue rather than a product issue, but it is worth noting because hazmat shipping adds time that standard ground shipping estimates do not account for. Ordering with a week or more to spare is the practical standard.
Finally, ordering the same fuel indefinitely without checking whether it still matches the build as the engine evolves is something experienced racers occasionally fall into. An engine that has gone from mild modification to a more aggressive tune, or a sled that added a turbo kit, may have crossed an octane threshold that makes the previous fuel choice inadequate. Revisiting the Fuel Selector when the build changes costs nothing and catches the issue before the engine does.
Yes. The full Sunoco race fuel lineup is available online through Petroleum Service Company with shipping to homes, garages, and businesses across the United States.
Race fuel is classified as a flammable liquid and ships under hazmat regulations in DOT-approved containers. Reputable suppliers handle the compliance and packaging requirements. A hazmat surcharge applies and appears in shipping costs at checkout.
Yes. Home delivery is available from PSC. The delivery address does not affect eligibility as long as the order meets the carrier's standard requirements for hazmat shipments.
Most Sunoco fuels are available in 5-gallon pails and 54-gallon drums through PSC. Some products are also available in smaller quantities. Drums ship via LTL freight rather than parcel carriers.
Start with the Sunoco Fuel Selector. It walks through your engine's requirements and returns a specific recommendation. If the build sits outside the standard parameters, Sunoco's technical team is reachable at 1-800-RACE-GAS.
Knowing your compression ratio, boost pressure if applicable, racing discipline, and whether your engine has oxygen sensors or catalytic converters covers the variables that drive fuel selection. The Fuel Selector prompts for these specifically.
Buying race fuel online is straightforward once the fuel selection question is answered. Use the Fuel Selector to confirm the right product for your engine, then order through Petroleum Service Company with confidence that the full lineup is in stock, properly packaged, and shipped to wherever the build lives. If a question comes up during the process that the selector does not answer, Sunoco's team at 1-800-RACE-GAS handles the technical side and PSC handles the logistics.
