Is Mobil 1 5W-50 with Rally Formula on the Labels a Different Product?
Do you have more than one grade of Mobil 1™ 5W-50 oil? In other words, is there another Mobil 1 5W-50 oil that has a different specification or set of anti-wear ingredients than Mobil 1 5W-50 Rally Formula? I currently have two cases of Mobil 1 5W-50 oil that do not say "Rally Formula" on the label, and I am wondering if it has the same qualities and ingredients as your Rally Formula. The 5W-50 Mobil 1 that I have is specified as "API SM, SL/CF."
-- David Kelly, Vero Beach, FL
We only have one Mobil 1™ 5W-50 that meets or exceeds API SN, SM, SL, and SJ, and which has an API CF quality level. If the current label does not say “Rally Formula” it may be due to packaging design improvements, but the specification should be the same.
