Castrol Power 1 4T — 3 weights
Castrol Power 1 4T comes in 3 weights on our shelf: 5W-40, 10W-40 and 10W-50. 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.

Pricing is flat across the line: every one of the 3 weights starts at the same $22.12 for the 1 qt, so the weight you need costs the same as any other weight in Castrol Power 1 4T. The only price decision here is bottle size.
We carry 2 Castrol lines in total — Power 1 4T plus Actevo 4T. Power 1 4T is the dearest of them, opening at $22.12. Comparing across them is a fair way to shop; comparing a Castrol grade against the same grade from another maker is what the weight pages are for.
Bottle sizes in this line: 1 qt. We cannot confirm stock on any Castrol Power 1 4T part number today — call and we will check it against the distributor before you pay for anything. Prices shown are ours and come from the catalog, not a list price.
