Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Discover reliable, high-mileage protection with Pennzoil Full Synthetic 5W-30 High Mileage Motor Oil in a convenient 1 qt bottle. This premium oil is specifically formulated for engines that have accumulated miles, delivering the proven performance of a full synthetic blend while addressing the unique needs of aging engines.

Why this high-mileage, full-synthetic oil stands out

  • Top-tier protection for older engines: The high-mileage formulation includes additives designed to reduce oil consumption and help prevent leaks, keeping your engine running smoothly as it ages.
  • 5W-30 viscosity for all-season performance: Excellent cold-start lubrication in winter and stable protection at operating temperature in hot weather, helping minimize wear during start-up and throughout daily driving.
  • Full Synthetic stability: Superior oxidation resistance and deposit control help maintain a clean engine, reduce sludge buildup, and sustain consistent lubrication over time.
  • Wear defense where it matters most: Advanced film strength protects bearings and moving parts, supporting engine longevity on highway trips and urban commutes alike.
  • Seal-safe formulation: Designed to help with sealing integrity in higher-mileage engines, contributing to reduced drips and leaks compared to some conventional blends.

This 1-quart container is ideal for stocking up or performing quick top-offs between full oil changes, making it a practical choice for routine maintenance planning. Pennzoil’s trusted name signals durable quality you can rely on, especially when your vehicle has accrued miles and demands steady, dependable lubrication.

Who this is for

  • Drivers with higher-mileage engines seeking consistent protection without sacrificing performance.
  • People who want a readily available 1 qt option for convenient top-offs or emergency maintenance kits.
  • Owners of daily drivers, trucks, or SUVs that operate across a range of temperatures and driving conditions.

How it serves your maintenance goals

  • Maintains viscosity and lubricity under varying temperatures, reducing startup wear and supporting smoother engine operation.
  • Helps keep the engine clean by resisting sludge formation and varnish buildup, which can impair performance over time.
  • Offers a practical balance of protection and efficiency for aging engines, helping you get the most from your vehicle’s remaining miles.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a co-op banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
