Is there a problem mixing different brands of motor oil in my car engine so long as the mixed brands are the same viscosity (5W30) and API service grade (SM) ?

No problem. You can even mix different viscosity grades if you want.

Go for it. In one of my atv's, i have a mix of M1 4T 10w-40 (synthetic), valvoline 4T 10w-40 (dino), and shell rotells T4 10w-30 (HDEO). Runs great!

Do it up! Just have a general idea of what grade you want.

I'm looking at Mobil1 15w50 for my Nissan 300ZX. Curious if I used 3qts 15w50 and topped it off with M1 extended performance 0w20.

No such animal as 0W20 EP.

Would be:
14.95 cSt at 3/1 15W50/5W20EP
14.85 cSt at 3/1 15W50/0W20AFE

Basically is would be similar to a 40 Weight HDE0. Have you considered just buying a gallon of Shell Rotella T6 5W40 ($21) if you want a heavier 40 weight (compared to M1 0W40)?

Personally if you havnt tried it I think M1 0W40 would make an outstanding oil for that engine.

Thanks for the feedback. I'll keep mixing the leftover 0.9 quarts from those 5.1 quart jugs.

Yep, I definitely got that mixed up lol Sorry

I'm actually using T6 5w40 right now; seems to be working great! The oil is already a bit dark, so I'm sure it's been working on cleaning things up over the last 5-600 miles or so. Way too short of an oil interval, but I am curious to get something a tad lighter since I don't have a track driven twin turbo.

M1 0w40 has been recommended actually. Right now I'm trying to figure out some oils that may work from Motul (either 0w30 X-lite or 5w30 X-max seem to be the choice so far)

I am going to install an aftermarket oil pressure gauge soon, hopefully this week, so I may get the 0w40 M1 since it's readily available at Wal Mart.
