PennGrade Syn Blend 5w30 1 Quart

PennGrade Syn Blend 5W30 synthetic blend motor oil in 1-quart bottles delivers reliable engine protection across a wide temperature range for both gasoline and light-duty diesel applications. This semi-synthetic formulation balances the performance benefits of full synthetic oils with the cost-effectiveness of conventional mineral oils, making it an ideal choice for vehicles operating in demanding conditions where superior lubrication is required without premium pricing.

The 5W30 viscosity grade ensures excellent cold-start performance in winter months while maintaining stable film strength at elevated operating temperatures. The "5W" rating indicates pour-point performance at sub-zero conditions, while the "30" weight sustains protection during highway driving and sustained load conditions. PennGrade's semi-synthetic blend incorporates ashless dispersants and anti-wear additives formulated to reduce engine sludge, extend drain intervals compared to conventional oils, and protect against rust and corrosion in the crankcase and upper cylinder regions.

This product suits fleet operators, small equipment users, and classic vehicle owners seeking dependable engine lubrication without full synthetic expense. The 1-quart format provides convenient top-ups for routine maintenance, storage without excessive inventory commitment, and easy compatibility with bulk purchasing. Each bottle weighs 1.91 lbs and measures 4.3 x 2.5 x 9.2 inches, fitting standard engine compartments and storage shelves. Whether for preventive maintenance or addressing minor consumption between oil changes, PennGrade Syn Blend 5W30 motor oil delivers proven protection at accessible pricing.
