Synthetic vs Blend.. not the same age old question

[TallPaul]

Isn't there some requirement, say min 20% or so, for the oil to be labeled as a blend?

The 1.8T(Was looking at buying one of the Passat GLS 1.8T's but decided against it given all their electrical and sludge problems). Buying a used VW 1.8T is like playing Russian Roulette, given how people now a days don't take care of their cars. The turbo's don't cause the sludge if "IF" the people driving the cars took care of them. With a turbo a good synthetic and a low OCI(3-3.5k, maybe 4 really depends on your driving) you would be pretty sludge free.

Conventional at 3k OCI would be fine, but some of these people lease a car or keep it short time and beat the snot out of it with 1 or 2 oil changes in their ownership. The leave the problem to some poor individual with an out of warranty vehicle. I know to many people who run oil into a place none of us would want to. I was a 3k OCI Mobil 1 guy on my 01 Impala, a 5k Synpower guy on my 08 TC, and I just traded the TC for an 04 Xterra and doing a few 3k OCI's to make sure I get the [censored] out of the engine and then going for a 4.5k OCI with Valvoline Synpower and some YB Pennzoil.

Walmart jugs of Valvoline Synpower 5w30 for 21 bucks is a steal compared to what I used to pay for the quarts!
