Metal results show the oil lacks appropriate levels of anti-wear and detergent additives.
MaxiGuard Super Premium motor oil claims to be “SAE 10W-40” engine oil that is “a superior all weather motor oil made from the highest grade petroleum base stocks and designed to provide the finest performance” and “For all foreign and domestic cars.”
However, the Petroleum Quality Institute of America has issued a Consumer Alert on MaxiGuard MG SUPER PREMIUM 10W-40 Motor Oil. The MaxiGuard product may cause harm to an automobile engine and void warranties PQIA said today in a release.
“The viscosity results show this product is an SAE 10W-20, not a 10W-40.,” said the independent testing lab.
“Further, the volatility result does not support the use of ‘high grade’ petroleum base stocks. In addition, the metal results show the oil lacks the appropriate levels of anti-wear and detergent additives required for modern engines. The analysis also shows high levels of iron, aluminum, and silicon, which indicates this product, may contain used oil.”
PQIA says there are labeling issues, as e well. The label claims API service SA, SC. These are obsolete Service Categories the API cautions can cause harm to engines built after 1967. The label does not warn consumers of this limited use.
