- One driver documented a 20% improvement in city MPG with BP gas (20 MPG vs. 17 MPG on generic fuel)
- Another noted a 13% highway MPG advantage with Shell
- A controlled test comparing two tanks each of BP and Shell regular gasoline found Shell provided slightly better mileage (445 vs. 437 miles per tank)
These variations likely stem from differences in driving habits, vehicle age, and engine design. Your results may differ based on your specific circumstances.
Engine Performance Benefits
| Performance Metric | BP (Amoco Ultimate®) | Shell (V-Power NiTRO+) |
|---|---|---|
| Octane Rating | 93 octane | 93 octane (99 RON) |
| Deposit Removal | Excellent (focus on removing existing deposits) | Excellent (focus on preventing new deposits) |
| Horsepower Improvement | Up to 6.7% over regular gas | Up to 30hp in turbocharged engines vs. 87 octane |
| Best For | Older engines with existing carbon buildup | Modern high-compression or turbocharged engines |
Shell’s V-Power 93 octane seems to offer particular benefits for turbocharged or high-compression engines, like Ford’s EcoBoost. Meanwhile, BP’s Amoco Ultimate® provides balanced performance across a wider range of vehicles but doesn’t emphasize specific horsepower gains related to octane.
Long-Term Engine Health Effects
How BP Protects Your Engine
BP’s Invigorate® has shown impressive results in reducing valve-seat wear during extensive dynamometer tests. The company reports sludge reduction rates exceeding 80% with continued use.
This makes BP’s premium fuel potentially beneficial for:
- Older vehicles with accumulated deposits
- Engines that haven’t been maintained with premium fuel previously
- Vehicles that regularly experience stop-and-go driving conditions
Shell’s Engine Protection Strategy
Shell’s V-Power, tested over 500,000 miles across diverse engines, demonstrated minimal injector fouling over time. The formula also helps maintain catalytic converter efficiency by avoiding metallic additives that can cause damage.
A recent study noted that Shell’s friction modifiers reduced wear on fuel pumps by approximately 15% compared to industry averages, suggesting potential benefits for engine longevity.
Price Considerations and Value
Shell typically prices its gasoline 2-5 cents higher per liter than discount retailers, reflecting its premium additive package and brand positioning. BP’s pricing generally falls in a similar range.
Surveys indicate that 68% of Shell customers prioritize engine longevity over immediate savings, suggesting they see value in paying more for premium fuel. Meanwhile, BP’s loyalty programs like BPme Rewards attract cost-conscious drivers who still want the benefits of detergent additives.
The regional availability and pricing of each brand varies significantly:
- BP/Amoco has stronger presence in the Midwest
- Shell dominates coastal regions through partnerships with retailers like Kroger and Safeway
Corporate Approaches: Beyond the Pump
The companies behind these fuels take different approaches to their business strategies, which might matter to consumers who consider corporate values in their purchasing decisions.
Shell’s Balanced Energy Strategy
Under CEO Wael Sawan, Shell maintains a modest 1% annual growth target in oil and gas production through 2030. The company simultaneously invests in carbon capture and renewable energy projects as part of what it calls a “balanced transition” strategy.
This approach has resonated with investors, with Shell outperforming BP in stock performance this year. The company maintains significant quarterly share buybacks reflecting its commitment to shareholder returns despite increasing environmental regulations.
BP’s Recent Fossil Fuel Shift
BP has recently pivoted from its previous “Beyond Petroleum” position, announcing a 20% increase in oil and gas investments alongside a substantial reduction in renewable spending.
This strategic shift has drawn criticism from environmental groups and coincided with a significant year-over-year profit decline. BP’s current approach appears more focused on energy security concerns than on aggressive climate commitments.
Which Station Should You Choose?
Based on the comprehensive analysis of BP vs Shell gas, here are some recommendations for different types of drivers:
Choose BP (Amoco Ultimate® with Invigorate®) if you:
- Drive an older vehicle with potential carbon buildup
- Want a fuel focused on removing existing deposits
