Castrol Power 1 4T — 3 weights
Castrol Power 1 4T comes in 3 weights we carry: 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.
Ships direct from our distributor, usually 2–4 days. We confirm the date before we charge you.
Pick your weight
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. Every bottle in this line ships direct from our distributor, usually 2–4 days, and we confirm the date before we charge you. Prices shown are ours and come from the catalog, not a list price.
