“I push my engine to the limit, but Renegade E85 provides the protection!”

What was the car that got you into motorsport?

For Steve Giles it was his Dad’s Subaru Forrester SG5. When it came up for sale, he knew he could do something special with it – and get back into the sport he had loved years earlier.

He's our latest Featured Driver and he relies on Renegade Pro E85 to protect his engine!

The Sportsman ET Class continues at Santa Pod. Best of luck for the rest of the season Steve!

“We switched to Renegade and won the Championship!”

What did you do with the car you loved as a youngster?

Tony Higgs kept his 1977 Ford Capri and, over the years, turned it into an absolutely mad, street-legal, championship-winning monster!

He's our first Featured Driver and a huge fan of Renegade Pro E85!

The Street Eliminator series gets underway this Easter weekend at Santa Pod. Good luck Tony and team!

This offers incredible value for money from such a high-performing additive. For very high power applications, it can be used as concentrated as 35 litres to offer the biggest punch.
