So from my understanding, you bought a 7.0 premium vehicle, grinded to 9.0, but started losing SL at 9.0 and your NEW PLAYER that don’t have the mechanics/skill/understanding down yet…yeeaaaaah Top Tier is a mess at the moment with repair costs and SL income. If your not premium and have constant unlucky/bad games, you won’t make SL but rather lose SL. Since your premium, you shouldn’t be losing that much, but rather earning a lot of SL per game… But since your new, you will not survive top tier yet until you learned your enemy tanks/planes weaknesses, good/bad spots in maps, know when to destroy tank’s barrel so you can live and have a chance to destroy enemy without worry he will fire back, mechanics etc…etc…these learned skills/mechanics will help you survive and carry games and will profit more SL. But you learn them from the playing rank 1 vehicles and through the grind. If you skip, just asking to be jumped on with no idea how to survive and lose SL. Premium will only give you a 100% bonus on SL and RP rewards every match you play and grind faster. You still need to earn SL regardless if your premium or not to play the vehicles you want. That’s just how the game is designed, it is a F2P game. Gaijin has to make money somehow. Your welcome to pay them by buying SL with real money, your money. Either that or learn how to earn SL by playing better, learning and using premium account to your advantage while it’s still on. Using a premium vehicle also gives bonus reward, so there’s that. That’s all premium is.
I shown this before on another thread but seems relevant to share it here too.

Image above, I am premium, didn’t use premium vehicles. However, I lost a big chunk of my reward due to repair cost and ammo refills. But that’s due to the amount of vehicles I used for trying to win yet was defeated. Kept 1,618 SL in total out of 56k SL earned.

Image here, I died once, respawned again on 2nd vehicle and carried the game. I did well, won, repairs and ammo cost were minimal and kept 53k SL of 61k SL due to less vehicles used and surviving. If I were not premium, I wouldn’t make this much. Maybe would of earned around 30k SL and pocketed 23k SL due to repairs/ammo.

This one, premium saved my SL and still earned 11,759 SL to keep even though I earned 36k SL. If i weren’t for premium, I’d lose around -3k SL or more at Br at 9.0+. This was a bad game, but I had worse ones where I died a few times with 0 kills or anything then I truly lost around -20k SL. Worst matches.
You make SL by destroying players, getting achievements during battle, capturing zones, and not dieing and winning etc… 0 deaths = no repairs. You get a bonus % on SL if you win a match as well. Premium is also a booster for rewards. If defeated, you go home with decent SL or almost empty handed or with -SL instead.
