What is the best shock oil for a 1/8 buggy?

We count what racers run, we don't test oils, so this is popularity rather than a test result. Team Losi Racing, Team Associated and Ultimate Racing are the most popular brands, at 112, 111 and 104 racers.

What weight shock oil do racers run in a 1/8 buggy?

Most commonly 550 or 600 cSt in front and 500 cSt in the rear. Racers who use wt most often run 40wt front and 40 or 37.5wt rear. Buggies usually run the rear a step lighter than the front.

What weight shock oil do racers run in a 1/8 truggy?

Most commonly 600 cSt in front and 550 cSt in the rear, a step heavier than buggies. Truggies are a smaller group in our count, about 120 racers per end.

Do nitro and electric 1/8 buggies use different shock oil?

Mostly the same brands. TLR and Associated lean electric in our count, and XTR leans nitro, but most brands have racers in both.

Is wt the same as cSt?

No. cSt is a measured viscosity, and wt is a brand's own scale, so 40wt from one brand isn't always the same as 40wt from another. Check the brand's chart, or our shock oil converter, before switching.

Most popular shock oil brands for 1/8 off-road

This list covers brands with at least 20 racers. Each racer picks the weight, so the buttons go to a brand's range rather than one bottle where the store allows it.

First by one racer, so the top three are close to a tie. 82 of its 112 racers run electric. Its most common car is the Arrma Typhon TLR Tuned, at 19 racers. TLR sells its oil in wt, in 2oz and 4oz bottles.

Mostly in Tekno's own cars, the EB48 2.1 and 2.0 lead, and mostly electric, at 18 of its 22 racers. Tekno doesn't sell shock oil on its own, so the button goes to the closest match: PT RC's 550 cSt, another oil mostly run in Tekno cars.

Most common shock oil weights

Weights are counted apart from brands. A racer counts once per weight at each end, and cSt and wt are kept apart because wt differs between brands. About two-thirds of racers enter cSt. The three most common weights at each end are listed, with racer counts.

1/8 buggies

673 racers entered a front weight in cSt and 391 in wt. The rear usually runs a step lighter than the front: 550-600 cSt in front, 500 cSt in the rear.

	cSt (racers)	wt (racers)
Front	550 cSt (189) 600 cSt (183) 500 cSt (139)	40wt (111) 45wt (95) 42.5wt (76)
Rear	500 cSt (238) 450 cSt (168) 550 cSt (156)	40wt (123) 37.5wt (102) 35wt (91)

1/8 truggies

119 racers entered a front weight in cSt and 73 in wt. Truggies run a step heavier than buggies at both ends: 600 cSt in front, 550 cSt in the rear.

	cSt (racers)	wt (racers)
Front	600 cSt (32) 650 cSt (27) 500 cSt (25)	40wt (17) 50wt (15) 42.5wt (14)
Rear	550 cSt (42) 500 cSt (32) 600 cSt (23)	35wt (19) 45wt (15) 40wt (15)

How we counted

We count anonymous totals from setups saved in the app for 1/8 off-road buggies and truggies, nitro and electric. A racer counts once per brand, and once per weight, no matter how many setups they've saved. A value only counts if the racer entered it themselves, not if it came along with a copied setup. Store details come from each store's listing.
