Can SynLube Lube-4-Life be used as a replacement for all SAE 5W-20 Oils?
“All SAE 5W-20 oils” is a very broad category. SynLube Lube-4-Life can be used in engines that call for a SAE 5W-20 multi-viscosity grade oil meeting API SM quality levels. SynLube Lube-4-Life can also be used in all gasoline engines that call for an API SM, SL, SJ, SH, SG, or SF quality oil. That covers a lot of engines. If you are not sure if SynLube Lube-4-Life is appropriate for your application, call SynLube, Inc. at 1-800-SYN-LUBE. To familiarize yourself with the reason why SAE 5W-20 oils are recommended for some engines in USA, while the OEM of the engines recommend other SAE grades in other markets, please read our article (SAE 5W-20). http://www.synlube.com/sae5w-20.
