Pennzoil Platinum High Mileage Full Synthetic 10W-30 Motor Oil for Vehicles Over 75K Miles (5-Quart, Single Pack)

Full synthetic 10W-30 engine oil made from natural gas, not crude, using Pennzoil's patented gas-to-liquid PurePlus Technology.
Designed for for vehicles with over 75,000 miles.
Pennzoil Platinum High Mileage 10W-30 keeps pistons up to 45% cleaner than the toughest industry standard (Based on Sequence IIIH results).
No other leading high mileage motor oil provides better protection from friction (Based on Sequence IVA wear test using SAE 5W-30).
Formulated to deliver less oil burn off than high mileage motor oils made from crude oil.
Helps protect engines from loss of horsepower.
Single 5-quart bottle with ergonomic design for easy handling and pouring.
Provides faster low-temperature oil flow and protects in extreme heat.
Pennzoil is the first motor oil made from natural gas, not crude—PurePlus Technology converts pure natural gas into high-quality, full-synthetic base oil that's crystal clear and contains fewer impurities than other traditional and synthetic motor oils.

One 15 fl oz bottle of STP High Mileage Oil Treatment + Stop Leak.
ZDDP oil additive prevents wear to protect your high-mileage vehicle.
High-viscosity formula creates a thick cushion between moving engine parts to reduce friction.
Leak stopper helps prevent engine leaks, noises and smoking and helps to rejuvenate seals and gaskets.
Add this oil treatment to engine oil during every oil change.

Engineered to work with High Mileage Motor Oil to provide continued protection for vehicles with 75,000 miles or more.
FRAM High Mileage filter contains a cartridge of proprietary detergents and compounds that maintain viscosity, reduce corrosive wear, neutralize acids and keep engine component cleaner.
Designed for drivers who need to keep their older vehicles running for the long term.
SureGrip anti-slip texture makes changing FRAM oil filters quick and easy.

Replaces hardened or cracking valve cover washer seals that allow vacuum leakage and degrade engine performance.
OE-style seal profile and durometer ensures proper compression seal between attaching hardware and valve cover.
High-quality seal material resists engine heat and oil degradation.

High-tech low-friction motor oil based on synthetic technology..
Outstanding protection against wear, reduces oil and fuel consumption and ensures fast oil penetration of the engine.
oil change intervals of up to 30,000 or 50,000 km or every 2 years for low mileage drivers are thus possible..

High Mileage solution to protect against power robbing friction heat and wear.
Restores performance in engines due to wear and oil consumption in older engines.
Revitalizes seals to help stop oil leaks and prevent them from ever occuring.
Powerful detergents to remove and prevent oil sludge, use during your next oil change or between changes to replace lost additive content.

Reduces sludge buildup and prevents oil coking.
For repeated use, change oil every 3,000 miles on most passenger vehicles by substituting 1 quart of motor oil with Dura Lube Sludge Away. Continue using until sludge appears to be reducing. Check oil pan to review sludge consistency on discarded oil.
For more severe sludge build up, change the oil and add Sludge Away engine product every 1,000 miles.
Repeat application as needed until performance and oil color returns to normal.
oil color should be amber to a dark brown, not black.
Sludge Away engine product works with all types of motor oils including high mileage and synthetics.
