Pre-start checks
What does a fuel stabilizer actually do?
Gasoline starts to oxidise within weeks of leaving the pump: light compounds evaporate, heavier ones turn to gum and varnish that coat carburetors and injectors. A stabilizer bonds with the fuel and interrupts that chemistry, so the tank you park in autumn still holds usable, pourable fuel in spring.
How much do I pour per gallon?
Every bottle on this shelf prints its own measure on the label, and most sizes have a dosing chamber or marked cap. The exact ratio also sits in the listing each red button opens — check it for the bottle in your hand rather than guessing from memory.
How long can fuel sit once treated?
Long enough to cross an off-season comfortably — the Storage line is formulated for month after month of sitting, and the label on each bottle states the period it stands behind. Untreated fuel, for comparison, can start degrading in a matter of weeks.
Can I pour in too much?
The formulas are forgiving — a generous pour is not a problem for the engine. Stick near the label rate anyway: extra stabilizer past the recommended dose protects no better, it just empties the bottle faster.
Stabilizer or fuel-system cleaner — which one do I need?
They answer different mornings. A stabilizer protects fuel that is about to sit; a cleaner (our In-Season and Fast Fix bottles) rescues a system that already ran on neglected fuel. If the machine is headed for the corner of the garage — stabilize. If it came out of the corner grumpy — clean.
Which bottle is mine?
Answer one question: what is the engine doing next month? Sleeping — Storage. Floating — 360 Marine. Compression-fired — the diesel shelf. Working weekly — In-Season. Refusing to start at all — the small-engine rescue aisle. The picker further up this page walks the same logic.
Where do the prices and stars on this site come from?
Straight from each product’s live retail listing — the same page the red button opens. The shelf currently counts 358,478 ratings across 42 products; when the listings move, the site is rebuilt to match.
Do you sell or ship anything yourselves?
No — nothing is sold on this site. Every purchase, payment, delivery and return happens with the retail partner whose listing the button opens. Think of this place as the organised shelf, and the partner as the till.
