Shell Spirax synthetic transmission fluid demo

Shell used a specially designed transparent gearbox to demonstrate that, within the same timeframe, for both cold starts and fully warmed up conditions. Shell Spirax S6 synthetic oil lubricates all the critical parts of the gearbox while the mineral based oil lubricates the gearbox much less evenly.

I've had a garage for 30 years, I remember rep's from oil and addative companies used to come around with see through perspex gearboxes you could turn by hand and demonstrate how much better their product clinged to the gears whilst turning etc, they became very reluctant to empty these demo box's and let me fill them with oil from my workshop...

This music is pretty intense for what’s. Going on 😅

A good synthetic oil is worthwhile, especially if the gearbox type is known for problems. I had various Rovers with the R65 gearbox for hillclimbs and sprints and went through probably 4 or 5 gearboxes. Never had a single problem after I changed to synthetic oil

The large gear might not have had a full film build, but the smaller one was definitely completely covered and would have lubed up everything fine

I'll probably never buy this product but it's always nice seeing these mechanical infromative videos.

We watched a 3-minute ad from Shell, voluntarily 😂

So they are comparing a 5w-30 oil with a SAE 30... that's like comparing oranges to apples. If they wanna show "the benefits of synthetic oil" at least show 2 oils with the same viscosity.

[seekter-kafa]

i love it when they say 'typical' like every oil is the same, and all oils are compared to 'typical'... i would like 3 liters of typical, please

You guys need to do full plant inspections on all of Dilmar Oil's plants. Their regional manager has them doing some low down dirty stuff with their Shell products, the latest being taking Formula Shell 10-30, combining it with Motorcraft Super Duty 10-30 and trying to pass it off as T5 Rotella 10-30.

Very nice unbaised comparison!!
You are comparing a synthtic gear oil (over 90% of trans oils in market are synthetic) with a very rare hard to find mineral gear oil.

This film shows:
1 you put more spirax than other oils
2 spirax is waterlike and perhaps provides less protection on high temperature or loads, considering gear tooth are drained almost immediately after leaving oil pan.

Shell Indonesia..

Saya Pakai Shell baik Pelumas dan Bahan Bakar sejak 2010 .. Pemakaian kendaraan saya Pribadi

Memang lebih boros tapi nyaman dan wangi.

Kapok pakai Enduro dan Pertamax, Mesin Jebol ..

Tapi sekarang Motor2 Inventaris cocok pakai Mesran..

It was a demonstration of how the fluid's viscosity would behave at cold temperatures without having to chill the whole apparatus. The oils weight is it's viscosity at operating temperature, in other words the two different oils should have the same viscosity at operating temperature. The gearbox or engine manufacture determines what weight to put in it by calculations with a fluid at that expected viscosity. One of the benefits of synthetic fluid is that the viscosity is much more stable over a wider range of temperature, which means the cold synthetic is much closer to operating viscosity than the cold conventional. Conventional thickens up more than synthetic with the same drop in temperature. What they are claiming is that they measured their synthetic fluid viscosity at cold temps and measured conventional viscosity at cold temps. Then they mixed the demo fluids to match those measured viscosities at room temp.

If my truck has been running fine for a million miles on regular old gearbox lube, then I'd say the difference is so minute it is practically immeasurable.

Reminds me of the Lucas display at the parts store.

For transmissions always use the original oil. This applies especially to VWs, yes it is around 20$/L and a MK3 Golf gearbox has around 3.5L of oil capacity so it's 80$ every 60k miles, I don't think it's that much, another gearbox is more expensive than using good oil.

[YoungXelDong]

I dont know why this was recommended to me but from now on ill try synthetic oil on my joints

[pavelcar]

С 80х Ауди использует синтетику, и эти МКПП до сих пор исправно служат!

[ianco]

SAE 5W-30 and SAE 30 have big difference so its obvious even without any video which is much thicker and atf usually have lesser viscosity

[kemottomtr]

It doesn't matter if gearbox oil is syntetic or not. What they show is just difference in viscocity. Thicker oil stays on theeth much longer and thats why after couple of revs its missing unde the sprocket. I wonder how it looks under higher RPM. My guess is that mineral oil will flow through inner wall as one uniform stream and syntetic will just splash all over
