Is Durablend better than WB?

Not open for further replies.
Advance is selling Edge for 5qts and filter for $25. Now you get a rebate of $15. That means each qt. $2.00 plus the extra govt. share. Castrol has the rebate going this month. So I ask you why buy a blend which by the way has no moly, when you can get the real thing for $2.00 a qt.?
True. It is also true that I got my five quarts of Edge for about a buck fifty each, from AA, using their $10.00 coupon in connection with the Castrol MIR. I also bought twelve quarts of Valvo Durablend for less than a dollar a quart. I bought two cases on clearance from Meijer, and then sent off for the Valvoline MIR of $15.00. It has truly been a year for cheap oil, in contrast with the last one. I am currently going through ~70 qts/yr, so I have no problems with accumulating a large stash. Make hay while the sun shines.
Tell me about it. I have 15qts of M1. 15qts of Pennzoil. 10qts of m5000. 5qts of Quaker FS. 6qts of Edge. 6qts of syntec. and 8qts of Delvac.

It has more detergent in the add pack and it also uses a different detergent add pack than Premium conventional. It has 30% GP III blended into its GP II base. The rest is pretty much the same.

Well, because it has 30% GP III, the 100C cSt is very slightly higher,(10.84 vs 10.67) the 40C cSt is about 2 points lower,(69.74 vs 71.45) the HTHS is the same.(3.0) The GP III gives it a little better NOACK.(10 vs <15) The heavier detergent pack gives it a little better base number.(8 vs 7.5) if you think that is better. SA of both is 8. This is for 10W-30. Similar for 5W-30.
Frank, Sorry! I was replying to hpicris and his enumeration of his stash, not you. I actually think the Durablend sounds pretty good, based upon your post above. Since you are here, I did want you to know that I ran my '99 Accord about 6K this summer on M1 EP 15W-50. Car seemed fine, and I really couldn't detect any loss in fuel economy. I know you prefer the regular flavor to EP, but the EP was clearanced dirt cheap this spring at Meijer and Target, so I have a small sub-stash of it. I bought and used it largely based upon your posts. I would not use it during the winter, although you do, and it is not a whole lot warmer in winter where you live than it is here.
I have had extreme service from the M1 15W-50 for the last 19+ years. drive It appears that Valvoline took the Premium Conventional GP II base oil, added some(30%) Synpower GP III base oil and tweaked the detergent package(more calcium, no sodium, 490 magnesium) What I wish they had done was to use the MaxLife base oil(up the HTHS to about 3.2) Because they wanted to stay GF-4, they didn't up the ZDDP as they upped the detergent package. That is probably something normal shrug people would be happy about.
