This is the correct oil for filling the dashpot dampers on all 1945 and later This is he correct grade for all SU and Zenith Stromberg carburetors including but not DS Racing's 1 cSt shock oil made especially for RWD drifting, the very low viscosity allows for a super soft damper setup which allows for more chassis roll and Premium mineral multigrade engine oil, high zinc, low detergent to suit Made from the highest grade Group 2 low sulphur oils. Penrite SU Dashpot Oil. 6 Mar 2018 I also swapped the SU carb that it came with for the one on it now because One thing I knew was the dashpot oil was important, but I did not know so I think there is both a viscosity and volume component, kind of like there 21 Jul 2017 Cavitation can happen when either pressures are too low or damping and oil viscosities (saturated vapor pressure) is too high. MANITOU: Oil They sell 2 types of oil – “SU Damper oil” which is straight SAE 20 monograde oil # BDR125S and “SU Dashpot oil” # BDP125S for pre-war SU’s without a damper ( SAE grade unspecified). The bottle shown in the test is labelled “SU Damper oil” so it should flow like any other SAE 20 at normal temperature – say 70 degrees Fahrenheit.

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. Used as such it works very well, especially where economy is the main goal and the car is driven very sympathetically.

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. If when you put the piston back into the dashpot you feel resistance from the oil before the cap rests against the dashpot, then you have sufficient oil to do the job properly. SU carbs are not that sensitive to oil level in the dashpots, and you've got the proper weight oil in there. All the oil does is regulate the carb pistons' movement during acceleration and prevent them from chattering during idle and cruise. If there's oil in there, you're OK. For initial setting of the carbs, refer to the owner's manual, as it provides the best starting point.

The Classic Zcar Club is a not-for-profit group dedicated to the purpose of preserving the classic Datsun/Nissan Z and other similar cars from Japan. 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.

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 1 Sep 2014 Not only that, but because the Mobil 1 15W-50 is a multi-grade oil, its viscosity is much more stable than the SAE20, so its viscosity tends to stay 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

characteristics slightly by adjusting the viscosity of the oil in the dashpot damper. SUs are set up so that a thicker oil will resist the piston's attempt to rise in the dashpot for just long enough that the engine's increased load (when the throttle is opened) will pull more fuel across the bridge; this enriches the mixture and temporarily bumps power Suspension Fluid Viscosity Chart. Some of you have changed out your suspension fluid to a heavier or lighter weight fluid or so you thought to change the damping of your suspension. The problem that comes into play here is manufacturers are not playing by any set of rules so it seems, Ones 5wt will be some others 15wt. It is only necessary to keep these tubes topped up with oil, leaving a little space for the damper. Any more oil will overflow and it will quickly get sucked into the engine and burnt. In the case of SU’s without dampers, they still require oil every 1,000 miles, but the oil merely lubricates the guide tube. It has no damping effect.
