Isn't 0w-20 a little too thin? Even though I live in Cali where it doesn't get too cold.

No, because the "0" is the cold viscosity.
It's even better for those who live in cold areas.
It's the number of the oil before the car is up to operating temps.
The important number is the 20.
It's the right number too!

I heard 2006 and newer tC use 5w-20
Should my supercharged 2006 tC using 5w-20 too?
I got my tC since May 2005.

SciontCya

Your 2006 should be using 5W20.
I'd use synth on the SC.

I got an 09, on the cap it says to put 5w-20 but i have some RP in 5w-30 in the garage.

Can I just use that instead?

If it's under warranty, and it is, no.
Will it harm the engine?
Likely not.
But, they say 5w20, so use 5w20.

its actually not under warranty... its a salvaged vehicle. so im good to go? lol

SciontCya

Up to you.
I'd still run 5w20.

Is there a reason no stores carry Royal Purple Max ATF? I looked 3 diff stores.

Kragen had 4 bottles and they don't stock it any more. Does it suck or something?

5W-20 gives you better gas mileage. 5W-30 gives you better engine wear protection.

Noob here. Just read the entire thread. Thanks everyone for all the great info. I'll add one thing: If you can, do your own oil changes because you'll know that everything that was supposed to be done was done. Dealers, Walmart, Jiffy, etc., have all been caught cutting corners by not doing the things they tell you they will do. It has happened to me enough times that I finally decided to never trust my vehicles to these places. First time it happened was in Spokane. I went to Walmart and got their top oil change/service on my truck. What they didn't know was that I was taking it from there to Jiffy to have the differential serviced (Wally doesn't do that). Jiffy found that the fluid in the diff was so burnt they had to flush it three times. They didn't charge me any extra for this, so there was no motivation for them to be messing with me. The tech said he could tell that no one had checked the diff recently. He also told me that he used to work at that Walmart and they routinely cut corners to get cars in and out. I went back to Walmart and told them what I had learned. They apologized immediately, refunded my money, and gave me a certificate for a free service in the future. It was clear this wasn't the first time someone complained about their practices.

So I stopped going to Wally and switched to Jiffy. Many years went by and then I started having transmission problems with my Volvo. The car had an oil change at jiffy two weeks before this happened. The first thing I did was check the fluid level in the transmission. It was fine but it was also total sludge. I drained it and pulled the pan and the transmission was beyond hope. This didn't happen in two weeks and I suspect it didn't happen in two years. If so, that would mean that this particular Jiffy Lube supposedly checked the transmission at least five times without telling me what they were seeing. My guess is they never check it.

When I was younger, I used to do everything on my cars and I never had problems like these. Life got busier, and the cost savings for DIY maintenance got smaller, and so I just turned everything over to the so-called professionals. My advice: if you have to use them, don't trust them. Make certain they do everything they are supposed to do by either watching them (Oil Can Henry's) or checking things after they get done. As for me, I'm back to doing it myself. Also, it may just be me, but there is a certain satisfaction that comes from getting you hands dirty now and then. Smelling like oil for a good part of the day is somehow an added bonus. So you end up saving a bit of money by DIY and then you get something that money can't buy as a reward.

I am going to switch back to conventional oil, since I don't have supercharger on my tC anymore.
