What kind of gas does a 6.2 L V-8 take?
Most 6.2-liter V-8 engines in modern cars and trucks run on regular 87-octane gasoline, but certain high-performance or specially tuned versions demand premium fuel. The exact requirement depends on the engine variant and model year, so always consult the owner's manual or the fuel filler label for your specific vehicle.
Understanding fuel needs across the 6.2 L V-8 family
Because the 6.2 L V-8 designation spans multiple makes and generations, fuel recommendations vary. The following guidance captures common patterns across major manufacturers, with emphasis on checks to confirm your vehicle's requirement.
General guidance for 6.2 L V-8 engines
Typical octane recommendations you are likely to encounter in U.S.-market vehicles are summarized here:
- Regular unleaded (87 octane) is sufficient for most naturally aspirated 6.2 L V-8 engines in everyday driving.
- Premium unleaded (93 octane) is required or strongly recommended for high-performance variants, forced-induction versions, or engines tuned for higher compression to prevent knocking and preserve power.
- Some models may be flex-fuel and are compatible with E85 (85% ethanol); look for a flex-fuel badge or the fuel-cap label to confirm, and follow the manual's guidance on ethanol use.
Always verify the exact fuel requirement for your vehicle by consulting the owner's manual or the fuel-filler door label, as octane needs can differ between trim levels and years.
How to confirm the right fuel for your vehicle
To avoid misfueling, check these quick references: the fuel filler door label often lists the recommended octane; the owner's manual specifies minimum octane and any premium-only requirements; and the vehicle's onboard computer may flag improper fuel if you attempt to use lower-octane gasoline. When in doubt, err on the side of premium if the manufacturer calls for it for towing, performance, or high-compression operation.
Summary
In short, a 6.2 L V-8 can typically run on regular 87-octane gasoline, but high-performance variants and certain engines require premium 93-octane fuel. Always verify with official documentation for your specific model and year, and consider fuel alternatives like E85 only if your engine is flex-fuel capable.
Can you run a 6.2 on 87?
The Chevy Silverado base configuration can operate effectively with 87-octane fuel. However, if you upgrade the engine to the 6.2L, you might be wondering if the Chevy 6.2 needs premium gas. Yes, the Chevy 6.2L engine has a higher compression ratio, and 93-octane gas is recommended.
Can you put regular gas in 6.2 L V8?
You should use premium gasoline if you drive a Tahoe or a Suburban with a 6.2-liter engine. These SUVs can use regular gas, but it might decrease their fuel efficiency. You can use regular unleaded gasoline if you drive a Tahoe or a Suburban with a smaller engine.
What type of gas should I put in a V8?
premium unleaded gasoline
However, if your vehicle has the 6.2-liter V8 engine with DFM technology, premium unleaded gasoline with an octane rating of 93 is recommended for optimal performance.
Is the 6.2 L V8 gas?
The 6.2L flex-fuel gas V8 is the standard engine in F-250 and F-350 models. It's engineered to deliver peak torque at lower rpm and generates high torque throughout the midrange of the power band.
