,we all make mistakes,but it takes a Man to admit when he does.Just trying to help so people don't get the wrong impression on Mobil 1,and no,I do not work for or have any interest in Mobil/Exxon.

Just an observation - When I push my car hard (mountain drive or track) with Mobile 1 5w30 I found that my oil pressure would fall in the toilet at idle - .25 bar or less. Once I let it cool it would again rise back up to normal - about 1 bar. Needless to say this made me really uncomfortable!
I have since changed to Redline 10w40 and have not seen the problem again
For those of you that are wondering why Mitsubishi recommends 5w30, I believe that it has to do with their belief that we are going to thrash on our cars when cold. Since Mitsubishi can't trust us to warm up our cars before driving hard they give us an oil with a low cold viscosity. The 5 represents the weight of the oil when cold, and since this is a low viscosity, damage and wear when cold is reduced.
BTW -- the 30 or in my case 40 in 10w40 in the viscosity rating when hot. One of the reasons for my better oil pressure readings. That and I believe Redline is just better oil

IN SUMMARY:
1. Ester-based oil 'clings' onto your engine parts because of its polar nature. Therefore in situations like cold-starting your engine, when the oil hasn't been pumped thru the system, your engine will still have a thin layer of oil (because of the said polar nature).
2. Ester-based oil is more resistant to shearing.
3. There's a third one which I don't remember now
I came across this couple of years ago when searching more on Motul, which IMHO is the best oil on earth for vehicle applications.
Oh yeah so my answer to the question of this thread is: Motul oil.

because of this, mobil figured if you cant beat em, join em, and decided to do the same, which is why mobil one does not say synthetic, is says syntec or some other $hit, i forgot exactly what, they did the switch over as well because it cost less to produce.
in conclusion, royal purple is the only true synthetic that i can think of off the top of my head, if anyone disagrees with me or would like to add any additional input, id like to hear about it because id be interested in hearing how others feel about this

Once it doesn't freeze overnight anymore...probably around early May, I will once again switch to M1 10-30

BMW Motorsport performed a little test in which they took several crankshafts and dipped them into several different brands of motor oils from dino to full synthetic including Motul ester based motor oil. The crankshafts where all submerged for one hour, they where removed then where left outside in the elements for one month.
Only did the Motul ester based motor oil crankshaft did not rust. This was due to the polar bonding for the motor oil onto the crankshaft.
