Bel-Ray Thumper Racing — 4 weights
Bel-Ray Thumper Racing reaches across full synthetic and semi-synthetic in the bottles we hold, over 4 grades from 10W-40 to 15W-50. Within one line that makes it two decisions rather than one: the weight the manual specifies, and which base stock you want it in.
Ships direct from our distributor, usually 2–4 days. We confirm the date before we charge you.

Priced by weight: 10W-40 from $15.99 (2 sizes), 10W-50 from $26.99 (2 sizes), 10W-60 from $26.99 for the 1 L and 15W-50 from $16.99 (2 sizes). 10W-40 is the cheapest way into the line and 10W-50 the dearest, a $11 difference — which is not a reason to pick one, since the manual decides that.
We carry 6 Bel-Ray lines in total — Thumper Racing plus MC-4T, EXL Mineral, V-Twin, EXP and EXS Synthetic. Thumper Racing sits 5th of 6 on entry price, at $15.99. Comparing across them is a fair way to shop; comparing a Bel-Ray grade against the same grade from another maker is what the weight pages are for.
Bottle sizes in this line: 1 L. 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.
