Chevron Techron (fuel detergent additive) — positioned as containing the same detergent chemistry used in Chevron’s Top Tier gasoline.

Key Claims & Features (What It Does)

  • Detergent additives vs. fuel clean-ness: The video argues that the main difference between “regular pump gas” and Top Tier fuel is the amount/type of detergent additive.
  • Techron chemistry alignment: Chevron Techron is claimed to use the polyethramine detergent chemistry that Chevron says it invented (referenced as used in Top Tier fuels since 1981).
  • Regulatory context:
    • LAC (Lowest Additive Concentration) = the minimum detergent level allowed by the EPA.
    • Top Tier standard = a higher detergent level aimed at keeping injectors clean and reducing combustion chamber deposits.
  • How cleanliness is measured: Mentions the ASMD6201 intake valve deposit test and a Top Tier target of producing < 50 mg carbon deposits per valve.

Test Results / Numerical Findings (Quoted)

Using an AAA study and the ASMD6201 test:

  • Moving from LAC fuel → Top Tier fuel reduced intake valve deposits by 19× (not 19%).
    • Average deposits: 660 mg/valve → 34 mg/valve
  • Piston deposits decreased by 8% (reported alongside the injector/valve cleanliness improvements).

Price / Value Calculations (Given)

  • 12 oz bottle cost: ~$12
  • Covers: 12 US gallons
  • Cost effectiveness: ~$1 per gallon
  • Recommended usage frequency: once every 3,000 miles
  • Example cost in a real-world scenario (Boxster highway estimate):
    • ~1 cent per gallon (rounded up; described as “less than a penny per gallon”)

Practical Recommendations / User Experience Guidance

  • When to add it: “Easy way to remember” = add during an oil change, but in the fuel (not the oil).
  • Top Tier usage option: The speaker recommends Top Tier gasoline and suggests Techron is also useful even when using Top Tier fuel.
  • Top Tier station finding: Mentions toptiergas.com station finder.
  • Price check: Claims GasBuddy shows little to no price difference in the tested area between Top Tier and non–Top Tier stations (same price on the same corner in the example).

Pros (As Presented)

  • Large reduction in engine deposits claimed based on test comparisons:
    • 19× intake valve deposit reduction
    • 8% piston deposit reduction
  • Cost-effective: very low estimated cost per gallon when used ~every 3,000 miles
  • Broad compatibility: tied to Top Tier chemistry standards and meant to restore/raise detergent cleanliness
  • May reduce wear over time indirectly: the speaker claims their diagnostics see high fuel dilution, and that improving detergent cleanliness can help reduce dilution and therefore engine wear

Cons / Limitations (As Presented)

  • Not all “Top Tier” fuels are identical: the video notes variability in cleaning levels among Top Tier offerings.
  • No direct “Techron-only” engine test is presented in the excerpt:
    • Results are framed as improvements tied to detergent concentration (LAC vs Top Tier),
    • with Techron positioned as matching Top Tier chemistry.

Comparisons Made

  • LAC vs Top Tier gasoline (primary comparison)
    • Intake valves: 19× improvement
    • Pistons: 8% improvement
  • Top Tier vs non–Top Tier stations/brands
    • Example (Top Tier): Exxon/Mobile, Shell, QT (per speaker)
    • Example (not Top Tier): BP, Circle K, Speedway (per speaker)

Overall Verdict / Recommendation (Concise)

Recommended — the speaker argues that adding Chevron Techron is a low-cost, high-impact way to improve fuel detergent performance, based on large deposit reductions from higher-detergency fuel standards, and that Techron uses the same detergent chemistry associated with Top Tier gasoline.

Speakers / Perspectives

  • Lake (“the motor oil geek”) — primary speaker; provides the chemistry background, cites AAA/LAC vs Top Tier test results, discusses pricing, and gives usage guidance.
