SU carburettors are a brand of carburettor of the constant-depression type. The design was in To prevent erratic and sudden movements of the piston it is damped by light oil (20W Grade) in a dashpot, which requires periodic replenishment.

SU Carbs - Dashpot oil. This subject is a regular message-board poser. Many of us have touted our preferences and discoveries whilst playing about over the  SAE 20 engine oil is the correct grade to use when you top up. On older SU carburettors, which have a vent hole in the screw-in plastic top of the dashpot, the oil  SU DAMPER OIL is a mineral based oil containing anti-corrosion and anti-wear additives for the lubrication of pistons and dampers in SU and Stromberg  SU DAMPER OIL is a mineral based oil containing anti-corrosion and anti-wear additives for the lubrication of pistons and dampers in SU and Stromberg  For use both in earlier pre-war SU carburettors with 'USE BICYCLE OIL' on dashpot caps and later damped SU's and also Zenith CD carburettors.

On older SU carburettors, which have a vent hole in the screw-in plastic top of the dashpot, the oil level should be i in. (13 mm) above the top of the piston tube. On dustproof SUs, which have a hole in the dashpot neck instead of the top, the oil should be i in. (13 mm) below the piston top.

SU Dashpot oil - manufactured for the specific application of SUs in STANDARD applications. That is on engines that are completely standard as the manufacturer produced them. It is a little on the thin side, but the whole engine tuning data for each engine is based on using this oil. SU Carb Dashpot Oil The purpose of the SU damper is to retard the rapid upward movement of the piston on the rapid throttle opening associated with acceleration. This delay in piston movement causes a momentary decrease in pressure at the throat, thus achieving a momentary increase in richness much the same as with an accelerator pump. SU DAMPER OIL is a Mineral based oil containing anti-corrosion and anti-wear additives for the lubrication of pistons and dampers in SU and Stromberg carburettors. Application SU DAMPER OIL is suitable for post 1940 vehicles using SU and Stromberg carburettors incorporating a damper in the dashpot assembly. 3 in 1 or atf is way too thin. The oil reissts the upwards lift of the piston when the throttle is depressed. The slowness of the rise dictates the extra 'suck' on the main jet to increase fuelling during acceleration, this is the 'accelerator jet and pump'for an SU carb. We tend to use 20/50 oil. Fluid prices range from $5.75 to $8.95 for 125ml of official SU oil in a container with an official SU label, or $2 for a whole quart of automatic transmission fluid (ATF) or about $10 for a gallon of Marvel Mystery Oilthe choice is the reader's, but I know what I prefer! You can buy specific dashpot oil for the SU carburettors,..Penrite make some. Alternatively, standard 20W-50 engine oil is perfectly satisfactory with a standard engine. As for how much, unscrew the piston rod. Fixed jet carbs inject a squirt of fuel from the accelerator pump that is independent of the running temperature, whilst as Barrie has pointed out, using a monograde oil such as SAE 20 allows the SU to enrich the fuel/air ratio in sympathy with the running temperature due to the greater change in the oil’s viscosity over say a 20W/50 multigrade.
