Evans will compete in the Giro for the first time since 2010 when he held the Maglia Rosa for a day.
"I could stick with my normal programme that I do every year or try this different approach – which may be too much, but certainly enough," he said.
"I have always wanted to race again at the Giro, but after I raced it in 2010, I didn't get to the Tour fresh. I'm not saying that the Giro and the Tour together is too much. The illness and injury I had in 2010 made it impossible to judge."
The 36-year-old may seem to be past his prime after a mediocre season last year but the Australian still believes he can win another Tour de France despite Team Sky's domination.
Evans, the first Australian to win the Tour in 2011, could not repeat the feat in 2012 when he finished seventh overall behind BMC team mate and US prospect Tejay van Garderen, who took fifth place.
Evans, who also finished runner-up in 2007 and 2008, is determined to stay number one at BMC and have another tilt at a Tour triumph.
He said. "My situation is a bit strange because there are not many riders who perform better with two Grand Tours than one in their legs. In my situation, with the racing I missed last year, I need and I feel comfortable with this programme."
His objective for the Giro d'Italia, which runs from May 4-26, is simple: "To get back to my best," he said.
"Since the virus I had last year, I have had to change my approach to my work. It's difficult when you struggle to get to your best even though you are doing everything correctly. I am not coming to the Giro just for training. I don't know where I will be with my form, but for sure, I will give it everything."
This year Evans has taken third place in the Tour of Oman behind Sky's Chris Froome and Spaniard Alberto Contador but he was never in contention at Tirreno-Adriatico, finishing 22nd and almost 10 minutes adrift of Italian Vincenzo Nibali, and was outside the top 50 in his defence of the Criterium International last weekend.
