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.

Priced by weight: 10W-40 from $14.99 (2 sizes), 10W-50 from $25.99 (2 sizes), 10W-60 from $25.99 for the 1 L and 15W-50 from $14.99 (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 $14.99. 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. All 7 are available now. Prices shown are ours and come from the catalog, not a list price.
