Can I use 87 gas in a pressure washer?
Yes. For the Briggs 020206-0 gas pressure washer, regular 87-octane unleaded gasoline is the correct everyday choice; premium is not required. The key is safe fueling and using fresh fuel so the engine starts easily and runs smoothly (see the fuel and safety notes in the owner's manual).
- Use fresh, clean unleaded gasoline (87 octane).
- Avoid old fuel that has been sitting for weeks or months.
- Do not overfill the tank; leave room for fuel expansion.
- Never fuel indoors; fill the tank outdoors only.
- Keep fuel away from sparks, open flames, pilot lights, and other ignition sources.
- Turn the pressure washer OFF.
- Let it cool at least 2 minutes before removing the gas cap.
- Fill the fuel tank outdoors.
- Wipe up any spilled fuel before starting.
| Fuel type | Can you use it? | Best practice |
|---|---|---|
| 87 octane (regular) | Yes | Use fresh fuel; store properly |
| 91 to 93 octane (premium) | Yes | No performance benefit for normal use |
| Stale/old gasoline | No | Drain and replace with fresh fuel |
Using the right gasoline and following the cool-down and outdoor fueling steps reduces hard-starting, rough running, and fuel-related safety risks. It also helps protect the engine and keeps your pressure washer ready for reliable cleaning.

What is the PSI of a gas-powered pressure washer?
For the Briggs 020206-0 gas pressure washer, the rated outlet pressure is 2050 PSI. Gas-powered pressure washers in general commonly run from about 2,000 to 4,000+ PSI, depending on the pump and engine setup; always match PSI to the cleaning task.
Our owner's manual lists these key performance specs:
| Spec | Value |
|---|---|
| Outlet pressure | 2050 PSI |
| Flow rate | 2.0 GPM |
| Water supply temperature limit | Not to exceed 100°F |
Use PSI as your “scrubbing power” and GPM as your “rinsing power”. Higher PSI is not always better if it risks surface damage.
- 1,500 to 2,000 PSI: patio furniture, grills, vehicles (use wider spray and more distance)
- 2,000 to 3,000 PSI: decks, fences, siding (test a small area first)
- 3,000+ PSI: concrete, heavy grime (use the correct nozzle and steady technique)
The manual guidance for safe operation helps you get cleaning power without damage:
- Keep the spray nozzle 8 to 24 inches from the surface
- Start with a wider spray pattern and increase intensity gradually
- Keep the unit on a stable, level surface to control kickback
- Supply water at more than 3.0 GPM and at least 20 PSI at the washer end of the garden hose
- Avoid running hot supply water (keep it under 100°F)
Using the correct PSI helps prevent etched concrete, damaged wood fibers, and forced water intrusion behind siding. It also reduces pump stress and overheating; this model uses an automatic cool-down system that cycles water when pump temperature rises.

How to prime a Briggs and Stratton pressure washer?
To prime and start your Briggs pressure washer model 020206-0, connect the water supply first, squeeze the spray gun trigger to purge air, then press the primer bulb (cold engine) and start the engine. Priming helps the carburetor get fuel for an easier cold start; see the owner's manual.
- Connect a garden hose to the water inlet and turn the water on fully.
- With the engine OFF, hold the spray gun and squeeze the trigger until you get a steady stream of water (this bleeds air from the pump and hose).
- Confirm the spray gun has a working trigger lock/guard and do not secure the trigger open.
- If the engine is cold, press the primer bulb firmly about 3 times.
- Set the engine controls for starting (fuel valve ON if equipped; choke as needed for a cold start).
- Pull the recoil starter to start the engine; once running, adjust choke toward RUN as the engine warms.
- Make sure the water supply is cool (under 100°F) and has strong flow.
- Check the inlet hose for kinks and clean the inlet hose strainer.
- Inspect for a clogged nozzle; a blocked nozzle can mimic a priming problem.
- Look for high-pressure hose leaks or blockages.
- If the spray pattern is weak or erratic, inspect the wand and nozzle connection points.
| Symptom | What to inspect | Example part on this model page |
|---|---|---|
| Low pressure or surging | Nozzle or wand connection | Briggs & stratton nozzle B1236DGS |
| Leaks at fittings | Seals at connections | O-ring 190584GS |
| Hose leaks or restriction | High-pressure hose | 25'hose 84006753 |
Priming and purging air protects the pump and helps the engine start cleanly. Running without adequate water flow or with air trapped in the system can cause poor performance and can overheat the pump.
