Motorex Formula 4T — 2 weights
We hold Motorex Formula 4T in exactly two weights, 10W-40 and 15W-50, across 4 part numbers. Which one you want is settled by your owner's manual, not by preference.

Every Motorex Formula 4T bottle in this list states semi-synthetic on the product itself. Where a bottle does not state its base stock we leave the field blank rather than assume one.
Priced by weight: 10W-40 from $16.99 (2 sizes) and 15W-50 from $16.99 (2 sizes).
We carry 5 Motorex lines in total — Formula 4T plus Top Speed 4T, Cross Power 4T, Power Synt 4T and Boxer 4T. Formula 4T is the cheapest of them to get into, at $16.99. It is also the only semi-synthetic Motorex line we stock. Comparing across them is a fair way to shop; comparing a Motorex grade against the same grade from another maker is what the weight pages are for.
All 4 are available now. Prices shown are ours and come from the catalog, not a list price.
