I heard through the grapevine that they are using a very specific oil in them, that has a very short service life (I believe it is used in motocross race engines, requiring replacement after a few hours of use in that field). I am really interested if there will be a greater durability as we obviously do not have as much heat buildup that would break down the oil in the same fashion, or what sort of maintenance schedule sram is intending us to use on this fork.Posted 4 years ago
Lubrication oil is Maxima Maxum Ultra 0w30 (motorcycle engine oil). It does not have a short service life but because of the low amount of lubrication in damper side (5 ml) I would recommend frequent maintenance.iffoverloadMember
i think multigrades like 5w30 for example relates to the the oils viscosity at different temperatures
this is different from 5Wt fork oil as this will never be subject to high temperatures as in an engine. it is a specific viscosity and affects how the damping will operate.
the oil in the lowers is sometimes just lubrication for the bushings and I suppose you can use any decent clean motor oil if this is the case.
however some forks use the damping oil for lubrication as well in which case I would suspect a suspension oil would give you more chance of finding the damping charecteristics you want.Posted 4 years agonealyMember
Excellent 😀 Rockshox are using engine oil instead of damper fluid to lube the lowers. I’ve been using it in the lowers of my Reba’s for ages and it does make them feel smoother/plusher. I got onto it after seeing the enduro fork seal website recommending it and bods on MTBR doing far too much testing and proving it was fine and lubed better. Get fully synthetic and avoid extended life stuff, Mobil 1 is the best and I got 0w40 New Life from halfords http://www.halfords.com/webapp/wcs/stores/servlet/product_storeId_10001_catalogId_10151_productId_218746_langId_-1_categoryId_165581
Oil viscosity explained…
Most oils on the shelves today are “Multigrades”, which simply means that the oil falls into 2 viscosity grades (i.e. 10w-40 etc)
Multigrades were first developed some 50 years ago to avoid the old routine of using a thinner oil in winter and a thicker oil in summer.
In a 10w-40 for example the 10w bit (W = winter, not weight or watt or anything else for that matter) simply means that the oil must have a certain maximum viscosity/flow at low temperature. The lower the “W” number the better the oil’s cold temperature/cold start performance.
The 40 in a 10w-40 simply means that the oil must fall within certain viscosity limits at 100°C. This is a fixed limit and all oils that end in 40 must achieve these limits. Once again the lower the number, the thinner the oil: a 30 oil is thinner than a 40 oil at 100°C etc. Your handbook will specify whether a 30, 40 or 50 etc is required.Posted 4 years agonealyMember
Looks like Rockshox 0w30 is Maxima Ultra 0w30 ester synthetic motorbike engine oil, same bottle…Posted 4 years ago
Official line on this from SRAM, until 0w 30 Suspension oil becomes available use SRAM 3wt suspension oil.
The engine oil is a different formula as the application is different, heat, contamiation etc, you risk voiding your warranty if you use it, especially in the damper leg.Posted 4 years agosteel4realMember
I’d take Loco’s advice the RS 0W 30 stuff doesn’t appear to be available in the UK (or anywhere ?) yet.
The 3 WT stuff isn’t exactly common either but at least it is available (I think rear shocks used it ?)!
Love it – SRAM sell the forks but not the parts specified to service them 🙁Posted 4 years ago
Have the 0w 30 on back order atm, have 3wt stuff that use in rear shocks (Motul factoryline) v good high grade stuff or use the SRAM 3wt shock oil.
I know people have been using engine oil in the lower of older forks, and although it will work to a certain extent we’d always reccomend sticking with suspension specific oil as it’s designed to do the job.
You could use high grade olive oil if you wanted but wouldn’t work as well as suspension specific stuff 😉
Keeping an eye on my pikes as there isn’t a huge amount of oil in them and the seals are now a single wiper/oil seal and foam ring as opposed to the separte oil and wiper seal as fitted to the Lyriks, so it’s a good idea to stick to lower leg service guidelines.Posted 4 years ago
