Performance Oils For Buick Engines

Which Racing Oil is Right for Your Buick?

✔️ Choose GP-1 10W-30 if you’re running alcohol fuels, power adders, or high-performance applications that demand superior wear protection. This Pennsylvania-grade base synthetic blend delivers top-tier performance and durability.

✔️ Choose HR2 10W-30 if you have a classic Buick engine and want a conventional oil that enhances performance while including special storage additives to prevent corrosion during long periods of inactivity.

✔️ Choose HR4 10W-30 if you want the same protection and storage benefits as HR2 but prefer a full synthetic formula for greater thermal stability and durability under extreme conditions
