After being axed by Force India at the end of the 2011 season, and in the wake of spending a year on the sidelines, Sutil was finally given the nod to return to the Silverstone-based marque at the final test from late February.
A positive second debut followed with seventh place in the season-opening Australian Grand Prix, since when the 30-year-old has failed to catch a break.
In Malaysia, Sutil and team-mate Paul Di Resta retired with wheel-nut issues; in China, the German was rammed into from behind by Jean-Eric Vergne in his Toro Rosso, and then in Bahrain he suffered a lap-one puncture after being clipped by Ferrari's Felipe Massa which wrecked any hope of collecting points, ultimately finishing 13th.
"The start of the season was good, especially if you consider I had only two or three test days to prepare. Australia was a strong race and the best way to come back to Formula One," said Sutil.
"Since then I've been unlucky with being hit in China and puncture in Bahrain. I definitely missed out on a few good points, but these things happen all the time in Formula One.
"Sometimes you benefit from them and sometimes it goes against you instead. They all balance by the end of the year.
"I try not to spend too much time thinking about the negatives. I try to move on and focus on how to do better.
"If something happens, I think whether I did anything wrong, learn from it and avoid doing it again."
For this weekend's Spanish Grand Prix, Sutil is naturally hoping for a trouble-free run.
"It is important, after three difficult races without points, to finish without any incidents," added Sutil.
"If I do that, I should have the pace to be among the front-runners.
"I just have to do my job, avoid mistakes and hopefully my luck will change.
"Wherever we have gone so far, the car has been competitive, so the next few races should see us scoring points and close to the podium.
"It is still early in the season so there is more to come and the car is really fast. I'm sure we can recover the points we lost in the last few races."
Team principal Vijay Mallya appreciates circumstances have conspired against Sutil.
He said: "Adrian has shown his speed so far, but the luck has not gone his way.
"The last two races have been very frustrating because he's been the victim of other drivers' mistakes.
"Without these incidents he would surely have scored well in both China and Bahrain.
"His race pace in Bahrain was remarkable because he was one of the fastest cars on track."
