I'm not. Been saying this for years, its extremely overrated!

Saying not to use a full synthetic is joke. You just have to make sure you use a synthetic that is heavily fortified with zinc. i.e. Amsoil RD50, ARO, AMO, Zrod

We have been using the Amsoil in the Race Boat and ver happy with it.

Dik. Its was Saturday btw. I was resting up for a night out at the casino with your uncle who was asking about ya. My buddy was boxing there. TKO in the 3rd round. There was also a amateur bout in the bathroom there, which resulted in a TKO in the first round. Then back to the bar, for lots of ketel one. No oil talk last night lol

Awesome. For the record, my Loto mechanic used Valvoline 20w50 and said after 25 yrs it never failed him. He said all the other high $ oils could never replace consistent maintenance.

Curious, what do the Sterling race motors and comparable motors use?

In my quest for a quality oil, and from what I understand, synthetics do not breakdown like a conventional, when it comes to the viscosity improver additives. Mainly because synthetics don't need as much additive.

So, I was about to get some straight 50w dino oil, when I came across a DEAL! Oreillys auto parts had Valvoline VR1 FULL SYNTHETIC 20w50 on clearance. Reg price $9.49 per quart. On clearance for $3.49 a quart. WTF, you cant barely even buy walmart supertech dino oil for that price. So I hit up all the local oreillys buying whatever they had in each store, which wasn't much. After hitting about 6 stores, I ended up with 43 quarts of the 20w50, and bought 15 qts of the 10w30 for my dually. At least I have enough for 2 oil changes on the boat, and 2 on the truck for now.

They have it in 10w30 and 20w50. This is the stuff I bought

Looks like a very strong oil. According to the test of film strength I posted on page 1 of this thread, this oil ranked about the best. So did the conventional VR1.

I use the VR1 Race oil 30W dino.

The 20w 50 is on sale at Oreillys but there isnt any available in detroit area.

Always enjoy the oil threads. -Here a cut & paste of a post I made back in '06 about Brad Penn.

I'll share my experiences with Brad Penn oil.
Up until last summer (2005) I had been running Pennzoil 20-50 (engine builders recommendation) I change my oil every 10 hrs and it seemed to work pretty well, no oil pressure issues, oil temps @230 after an occasional hard run 260 (measured before the cooler)
Toward the end of last season I had switched to Brad Penn 20-50 and was not very impressed to say the least. In June I trailered over to Lake Winnipesaukee for Laconia weekend.I had just done a fresh oil change for the trip. We did a lot of boating the first couple days. After three days of running Brad Penn (8 hrs run time) I noticed a loss of oil pressure. My boat normally runs about 60 lbs after warm up while cruising. We were cruising along at no more than 4000 rpm when I noticed the oil pressure dropping. It dropped to 40 lbs, then 30 lbs, I backed down to 3500 and pressure dropped to 20 lbs.
I thought It was engine trouble and stopped for a while. Upon restart, oil pressure returned to normal, 60 psi but soon dropped back to 20 after temps warmed up to normal.
It appears that the Brad Penn oil was all done at 8 hrs and was breaking down at less than 220 degrees oil temp.
I've since changed to Mobil 1 (V-Twin) and all has been fine since. The Mobil oil seems to be pretty consistent, no pressure fluctuations at all and more oil pressure.

Take it for what it's worth, just my personal experience.

Joe, Awesome work, I've been running Mobil 1 15W50 Syn. for years and I'm shocked where it ended up on that list. I've never had any issues and have a stock pile of it so I will continue to run it for now.
