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

Meet Pennzoil Full Synthetic 5W-30 High Mileage Motor Oil in a convenient 5 qt capacity—a formula designed to protect aging engines while delivering the performance modern drivers expect. This full synthetic 5W-30 oil is engineered to work with a wide range of engines that have accumulated miles, helping you get more life out of your trusted ride.

Why this high-mileage formula stands out

  • Seal-conditioning for aging engines: this high mileage blend includes conditioners that help keep worn seals flexible, reducing oil leaks and consumption where older engines tend to weep.
  • Robust wear protection: a premium synthetic base resists breakdown under heat and stress, helping to preserve critical engine components from increased wear as miles add up.
  • Deposits and sludge control: advanced detergents keep engines cleaner, preventing sludge buildup that can sap performance and efficiency over time.
  • Optimized cold-start performance: the 5W-30 viscosity provides smooth lubrication during cold starts while maintaining strong protection during hot operating conditions.
  • Longer-lasting engine cleanliness: designed to minimize varnish and deposits on valvetrain parts, helping your engine run more quietly and respond with consistent power.

What problems it solves

  • Reduces oil consumption and leaks in high-mileage engines, thanks to seal conditioners.
  • Delivers reliable protection during temperature swings, improving cold starts and hot-day performance.
  • Keeps deposits at bay to maintain engine efficiency and responsiveness over time.

Who this is ideal for

  • Vehicles with 75,000 miles or more seeking enhanced protection and leak reduction.
  • Drivers prioritizing a single, reliable 5W-30 full synthetic oil for routine maintenance.
  • Owners looking for a oil that balances performance with the needs of aging engines without compromising on cleaner operation.

How to use

  • Check your vehicle’s owner manual for the recommended oil viscosity and change interval.
  • Use as you would with other full synthetic oils: replace the oil filter with every oil change, and fill to the correct dipstick level.
  • Dispose of used oil properly and follow local recycling guidelines.

Pennzoil Full Synthetic 5W-30 High Mileage Motor Oil 5 qt brings proven synthetic performance to engines with miles on them, delivering dependable protection, cleaner operation, and peace of mind for daily driving and longer trips alike.

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.
