Specifically the 10w30. This is a General Petroleum synthetic blend oil that we get in bulk at work for our gasoline vehicles (along with 15w40 Delo for the diesels). I wish they would publish the HT/HS...
Performance 500 Motor Oils
5W20, 5W30, 10W30 GF-4/SM*, 20W50 GF-3/SL*
CUSTOMER BENEFITS
• Outstanding anti-wear protection
• Defense against thermal breakdown
• Cleaner engine and positive crankcase ventilation
• API SM, SL, and previous API “S” categories
FEATURES
Performance 500 Motor Oils are top quality automotive engine oils formulated with premium base stocks, shear stable viscosity index improver, dispersant inhibitor, wear control modifier, anti-sludge detergent, corrosion inhibitor, antioxidant, and a foam suppressant.
This special formulation creates a high viscosity index for GP’s Performance 500 Motor Oils, which guarantees low viscosities at low temperatures for easy cold starting and steady warm up; while maintaining viscosity at high temperatures for improved oil economy, fuel economy, and forming the sought after protective film over engine parts.
Anti-wear additives offer outstanding wear protection as engine parts slide smoothly against each other there-by preventing scoring.
GP’s Performance 500 Motor Oils contain a high level of dispersants protecting against deposits and sludge formation in stop-and-go driving conditions. A recently developed friction modifier, dispersant, antioxidant, and corrosion inhibitor has proven to sustain high temperature operation, stop corrosion, forms an oxidation stability preventing viscosity increase, and eliminates oil gelling in the crankcase. All this allows your engine to provide maximum performance at maximum oil changing intervals.
APPLICATIONS
GP Performance 500 Motor Oils are recommended for all four-stroke gasoline engines used in passenger cars, light trucks, powerboats, motorcycles, and other mobile and stationary equipment. They are exceptional for high-revving engines in small cars and light trucks. All grades are specialty formulated for use in turbocharged engines.
