I've been wondering....
My oil consumption is not regular...
It seems it goes away more often in long runs, than in short trips.
So I start reading about oil gradient...
I always used 10w40 Selenia.
I know this is not very scientific, but when ever I check the stick, the damn oil just lets go a few drops to the ground... The damn thing seems thinner then water
When checking hot the damn thing's hardly visible....
Anyway.... This might all be me... so, lets continue.
I started wondering - I really don't need an oil that deals better with cold starts, so lets stick with the 10W.
Now, I should probably go with a 'W50 or a 'W60
So I started looking for alternatives in this table:
Looking at Selenia, they don't even care to divulge the viscosity at 40ºc
So let's look at the value for 100ºc
- Selenia 20K - 10w40 (that I currently use) --- ... / 14,5 (so this is the viscosity I'm looking to improve, right?)
- Selenia Abarth - 10w50 - - - ... / 17,5 This might work! But I can't find it in Portugal
- Selenia Racing - 10w60 - - - ... / 23,0 This might be a tad extreme, and really too darn expensive 49€ for 2L !!!!!!!!!!!!!!!!!
So, no more selenia for me! That's it!
I start looking at all the other brands, you are welcome to give me a hand, and none seem to give me more viscocity at 100ºc without making it too nasty at 40ºC.
So I stoped at Mobil 1:
- Mobil 1 - 5W50 - - - 104/17,4
When comparing with other oils, this seems more of a 10W50, than a 5W50, with that 104.
To be a true 5W I would expect something below 87 like the 5W40. But, it IS the SAME
oil, although multigrade, so we can't expect miracles!
But I think that works for me.
17,4 is ok, and 104 doesn't seem too extreme!
So I guess it might work well.
I found out this same oil - Mobil 1 5W50 (rally) - at a store here for 45€ 4L which I think is reasonable. Selenia 20k goes out for 50€ 5L.
Let's see if it works. And by work I mean, see if the DRINKING stops! :-)
