Motorex Cross Power 4T — 3 weights
Motorex Cross Power 4T comes in 3 weights on our shelf: 5W-40, 10W-50 and 10W-60. Inside a single line the additive package is the constant and the viscosity is the variable, so this is a one-decision page — match the manual.

Every Motorex Cross Power 4T bottle in this list states full 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: 5W-40 from $22.50 for the 1 L (2 sizes), 10W-50 from $22.50 (2 sizes) and 10W-60 from $24.99 for the 1 L (2 sizes). 5W-40 is the cheapest way into the line and 10W-60 the dearest, a $2.49 difference — which is not a reason to pick one, since the manual decides that.
Per litre the spread inside this line is real: the 4 L in 5W-40 works out to $21.75 a litre, against $24.99 for the 1 L in 10W-60. If your engine takes more than a couple of litres, the larger bottle is the cheaper way to buy the same oil.
We carry 5 Motorex lines in total — Cross Power 4T plus Formula 4T, Top Speed 4T, Power Synt 4T and Boxer 4T. Cross Power 4T sits 3rd of 5 on entry price, at $22.50. 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.
Bottle sizes in this line: 1 L and 4 L. All 6 are available now. Prices shown are ours and come from the catalog, not a list price.
