Yeah most of the time their products are only available in 1l canisters or 209liters or something. I always buy multiple 1l canisters because luckily shell is always very cheap.The problem with most Shell gear oils is that they are almost impossible to buy here for "Average Hans".
Most of them are only availabe in big jugs, not 1 Liter Bottles. Clearly aimed for repair shops as customers.
The second link you send has the cheapest redline mtl in the EU that i have seen so far so i will look into that.
I agree that their marketing is more focused on the average consumer. And their lubematch is also not very accurate some times.
However in my personal vehichles/motorcycles shell performed with the best results as far as i can personally observe. And most of the times its also the cheapest.
What i also like is that their specifications/approvals are always real certifiied.
