WHEN he revs up for this weekend's Supercheap Auto Bathurst 1000, Mark 'Frosty' Winterbottom will have determination in his eyes and E85 in his tank.
The 2015 V8 Supercar Champion is vying for Mount Panorama glory after last year's tremendous fight into second place with partner Steve Owen.
With his focus set sharply on keeping six-time Bathurst winner Craig Lowndes in his rear view mirror, Winterbottom said the Prodrive team was in with a "good chance" come this weekend.
"You're never too confident, and while our results haven't been the best leading in, our preparation has been strong," Winterbottom told ARM.
This year's strategy mimics that of 2015, but with added grunt to get them over the finish line first.
"We look at the final lap and work backwards," he said.
"Last year we were coming 24th with 72 laps to go and worked our way back up to second because we had a really aggressive burst towards the end.
"So heading into this year, our strategy is to be more aggressive."
Bathurst 2016 comes as the Queensland Government introduces mandatory levels of biofuel that Winterbottom applauded.
It means from January 1, 2017 certain fuel sellers will be required to meet specific targets for the sale of ethanol-blended fuels to reduce greenhouse gas emissions.
Winterbottom uses only ethanol blends for his personal cars and said despite the motor racing industry doing the same, everyday drivers still had a perception it was bad for their vehicle.
"It's just not true," Winterbottom said.
"That's why campaigns like this are so important because people need to be educated.
"I use it every day in my (personal) cars - always have, always will."
He said the ethanol blends of today are different to those of 10 years ago.
There are now extensive standards for blending ratios, technical specifications and labelling requirements, plus E10 now contains anti-corrosion agents.
"All products evolve and improve. If they didn't we'd still be riding around in a horse-drawn cart," Winterbottom said.
"You'll never convert the unconvertible, but we can try to educate people."
He said most vehicles today were built to run on ethanol blends and we need to bust the myth that E10 is bad for a car's engine.
"We're about to go at up to 300kmh for seven hours straight on biofuel - so if the engine can survive that, I'm sure it can survive 100kmh on the M1," Winterbottom said.
He encouraged drivers to visit the E10OK website where you can type in your vehicle registration, make or model and see if your car is E10 compatible.
