Does any one use full synthetic motor oil?

I am fully aware of the advantages of using full synthetic motor oil over non synthetic and the simple fact that the oil will not break down as quickly as non-synthetic motor oil.
In the past I have always used 10w30 non-synthetic.
My manual says to only use SAE oil with an SJ rating. I have some mobil1 15w50 motor oil with an SAE rating of SL, and SJ/CF.
I was wondering if anyone else uses full-synthetic motor oil and their impressions of of, or anyone that would not suggest doing this. Also I live in south FL so the ambient air temp is usually around 80-90 all year round so I think 15w50 would be fine.
Thanks
 
RockoT,
Have considered switching myself.

Several guys have and expressed good opinions.

People will prabably tell you the engine has to be broke in first.

I went to Mobil site and you won't see anything there confirming that.

Mobil 1 is the standard oil used by Porsche, Corvette and many others.

I beleive all Indy cars also use it.
 
I have been using mobil one full synth my whole life and I have always used dino oil fo rthe fist 1,000-2,000 miles of what ever I drive and than switch to full synth. I have heard that if you run a new engine with full synthetic oil that it will not seal completely or properly. BUT now a days some cars are rolling off the lot with full synth oil. I'm not sure if maybe todays engines aren't affected by oil types, but since I'm sure I will never really know, I always play it safe and switch to fullsynth only after breakin.

P.S. Today I did switch to full synth and will post up my opinions after a week or so.
 
We have been using fully synthetic 10W30 in our new and used gas powered pressure washer engines for some time now. I will swear a testimonial to the results...we change our oil every (30) days and we just don't have any problems associated with lubrication.

Now, convince a technician or a neighbor of a restaurant being cleaned that closing the van doors is NOT a good solution to a noise problem. We have a nice collection of broken crankshafts and camshafts as a result of INSUFFICIENT AIR COOLING.
