Been using 5w20 motorcraft syntecblend and 5w3o castrol syntecblend and both hold up well in super humid fla.OCI at 3500 to 4k due to terrible traffic and high heat all the time.I use it in a 4.6 crown vick with 101k.
Hi,
I've used the Castrol Syntec Blend twice, once mixed 50/50 with full Syntec and the UOAs came back excellent. In fact, the Blend alone did as good as the higher syn blend at 1/3 the cost.
I think the folks who blend their own are not getting anything for their trouble and cost.
Castrol Blend is only 5 quarts for $10.30 at wal-mart. Excellent oil for 5-7.k oci IMO...
Cheers, Bill

So far all of them seem to give good UOA's with a reasonable OCI. Motorcraft is developing a heavy following here as far as bang for the buck.
Motorcraft 5-20 and 5-30 are as good as any, if not better.

I have recently discovered that by buying a "blended" oil, you do not know how much synthetic is in the blend vs. how much dino oil, as there is no standard regualating this.
It is thus recommended to make your own blend by using dino oil and throwing in a quart of fully synthetic such as Mobil 1.
At least you know how much synthetic you are getting in your belend, and its not a guessing game.

Isn't mobil 7500 a Grp III oil plus a bit of Grp IV or V and even the Mobil 5000 is mostly Grp III? Which by most other companies' definition are full synthetic.
That's my vote!
DuraBlend SL 10w-40 carried A3 rating.
Yes and I bought 30 quarts. Sadly I do not see the A3 on the SM Durablend 10w40. There is still some SL out there though. Not too late to stock up.
This was recommended by one of those guys that writes a nationally syndicated newspaper column on automotive mechanical questions that are sent in by readers. He has over 25 years experience as a mechanic/journalist.
Besides, its only common sense. If i put in the fully synthetic and the dino, I know how much of eachj im getting. If you buy "blended" you dont know what % you are getting of the types of oil. Not trying to be rude or anything, but this isnt rocket science.

I agree ... blend your own & hopefully someday force these oil manufacturers to either stop selling it due to lack of interest or admit how much synthetic is in each quart.
Please post a link to your source's reports. I'm sure everyone on this board would be interested in reading what this nationally syndicated expert has to say.
You're a fairly simple guy, I can see that. And while I appreciate the fact that you share my concern for the unregulated amount of synthetic in blends, I disagree with the fact that you've come here and flat-out said that blends are worthless. That is ignorant.
Are your home-brew blends any good? Maybe, maybe not.
Are some synthetic blends any good? Yes, many of them are very good.
Do some suck? Yes, some of them suck.
This is why we have BITOG.
