Synthetic Motor Oil 5W-50
PETROFLO BRAND 5W-50 SYNTHETIC MOTOR OIL is manufactured from synthetic base stocks.
The unique combination of high performance synthetic fluids and proprietary additive systems enables
PETROFLO BRAND 5W-50 SYNTHETIC MOTOR OIL to offer advantages beyond their conventional
SAE viscosity grade counterparts. Conventional mineral oils thicken or thin dramatically with changes
in temperature. To compensate for this weakness, manufacturers add thickeners to conventional
multi-grade oils to slow thinning as engine temperatures rise. PETROFLO BRAND 5W-50
SYNTHETIC MOTOR OIL has a naturally high resistance to changes in viscosity due to temperature
and requires less of these thickeners. This results in a heavier, more stable protective oil film for
engine bearings piston rings than provided by similar SAE viscosity grade mineral oils.
PETROFLO BRAND 5W-50 SYNTHETIC MOTOR OIL meets or exceeds the requirements of:
European classifications ACEA A3/B3, A3/B4 and API SN, SM, SL, SJ.
PETROFLO BRAND 5W-50 SYNTHETIC MOTOR OIL protects engines up to 229°C (444° F.). It
contains fewer impurities, so it protects better than conventional oils in cold weather.
PETROFLO BRAND 5W-50 SYNTHETIC MOTOR OIL is fully compatible with mineral-based,
conventional, and synthetic blend engine oils.
PETROFLO BRAND 5W-50 SYNTHETIC MOTOR OIL is recommended for passenger cars, light
trucks, powerboats, motorcycles and other stationary and mobile equipment when engine life and
performance are important. Always consult your owners manual.
