Bought a couple of jugs of Valvoline SynPower 5w30 last time it was on sale at AAP and put it in the two Volvo 940 turbos I have. This is my first experience with Valvoline oil in many years. These cars have previously been run on GC (which I can no longer find locally) and PP, and would use no more (and usually somewhat less) than a quart over a 5K OCI. Both cars have now used over a quart of SynPower in about 1,500 miles. Has anyone else noticed an increase in consumption using this oil? I think I'm going to try some Rotella T-syn in them next to see if that quiets down the consumption (have used it before with good results).
Valvoline Syn-Power increased consumption

There's nothing wrong with Synpower; you just got the wrong viscosity.
5W-40 Synpower flows so well down the funnel, I can't even imagine the flow of 5w30; it's beyond my comprehension.

I'm thinking you just need a slightly thicker oil
5W-40 Synpower is readily available at NAPA.
No matter what the recommended viscosity is, if the engine is consuming oil, it's too thin. Besides that, Volvos have always been run on xxW-40 from what I gather.

Well, I got the Synpower half-off sale too, but got enough 20W-50 to add one quart to the 5w30 at oil change time to thicken it up a little. Works for me. Maxlife is another good, possibly better option.

That's not always the case. I've witnessed less consumption switching from 5w30 to 5W-20. The only explanation I have - is that 5W-20s are generally better-built oils.
Your engine must've sheared the 5w30 down to nothing. Your engine must be like a Cuisinart food processor.
Here goes...when switching oils one tends to discover one's engine will consume more...I don't know why just know it is so...In my embarrassing little lifetime I have owned two vehicles that did not leak oil or burn oil...A 1988 Ranger with 2.0L that I believe was designed by Mazda...and a 1982 BMW 320i...everything else I have owned consumes/consumed oil...My 2002 Prizm goes through a half quart every two to three thousand miles...when I change brands consumption goes up...consumption occurs mostly when a lot of highway miles have been achieved...

Rotella 5W-40 would be my next step too - since you ddin't mention doing an Auto-Rx cleaning.
