Hello Everyone, first off I wish to say Happy Good Friday to my fellow Christians, and if your not a Christian, Good Afternoon to you.
I have been on the boards picking peoples brains about these 2 oils for a little while now, and I am going to ask a few more Questions I would like answered, and some good opinions out there just for fun.
I have been using RL 5/30 for about 3,000 miles now, and though my car seems to love the stuff, I keep thinking in the back on my mind "man I have to order more" and at that moment I miss the fact that I used to be able to just go to the local store and buy the M1 that I used to use. Im not wimping out on the RL just yet though, but just more like gathering intel on the competition so to speak.
As I go back and forth on the manufactureres websites and doing my own searching I have come accross some minor details that I would like to know about.
1) Both RL 5/30 and M1 0/40 have a HTHS of 3.8 BUT done on diferent tests. I didn't know this. Can anyone tell me why this isn't a standard accross the board?
M1 0/40 tested by ASTM D4683, RL 5/30 ASTM D4741 what gives?
2) M1 has 1.3 of Sulfated Ash? What the heck is this stuff? I heard in large amounts its not so great in oil, so what does it do? Is it for anti wear or?
3) I am still stumped on the VI of these 2 oils. The M1 is 185 and RL is 162, so wouldn't the M1 be better than the RL in this particular area?
4) Vis @ 100c for M1 is 13.5 vs 10.6 of the RL. This also puzzles me because they both have the same HTHS rating (I think, but done by diferent testing methods) but have totally different viscosities at temp.
5) if M1 is a 0w when cold then why is the Vis @ 40c 75 vs RL at 62 while it carries a 5w? This also puzzles me. The 5w flows better than the 0w?
6) The Flashpoint of M1 is 230C while RL is 252C so for a turbo charged motor wouldn't the higher the flashpoint be better to protect the bearings of the turbo? Especially when the Turbo is shut off? Even with the turbo being water cooled, when the key is turned off, and even if you havent been driving hard, its still hot enough to the touch to burn the skin off your hand haha.
Some folks have read my posts and know I kinda am on the fence on stuff, so I don't want to seem like I am obsessing too much. Its just that if this M1 0/40 stuff aint that bad, and I can buy it at like 5 stores within 5 miles of my home, just sure would be more conveinent is all. I wont sacrifice protection for conveinence though, and that is why I am here again askign around. Thanks Guys.................Again
