Has anyone any experience with Castrol RS, a full race synthetic ?
I run it in a 30 year old inline 6 Ford engine, and it appears to work fine (10,000 miles), but then, I guess I would only really know if it didn't work
The other question I have, again based on cage engines, is I have heard that older engines and American engines in particular like to have more detergents in them. Odd as it may sound, the recommendation that follows this is to use a full synthetic, heavy duty, diesel oil. Again, I'm running this in a Rover V8 (Buick 215) with no problems so far (20,000 miles).
As far as gearboxes go, I can tell you that successive generations of Land Rover gearboxes ran 80W90, 20W50 and lately ATF. These are manual gearboxes, basically all the same, except that they added heavier synchro and another gear into the same basic casing. The lighter oils allowed more components to be crammed in while maintaining shift smoothness (such as it is
)
Right now I'm running the HD oil for each hole on the shovel, but after all I've read, and bearing in mind car experience, I think the next change will be to Mobil 1, Castrol RS, or a heavy duty synthetic diesel oil.
Comments ?

PS: Syn3 is what we would call over here a semi-synthetic (ie a blend of synth and dino)
