Andy Granatelli, a flamboyant race car driver turned businessman who became a household name with TV commercials for his STP fuel and oil additives, died Sunday at a Santa Barbara hospital. He was 90.

Granatelli died of congestive heart failure, his wife, Dolly, said.

Over the course of his career, he was inducted into 19 engineering and motorsport halls of fame, including, in 2002, the hall of fame at the Indianapolis Motor Speedway.

A natural promoter, he designed and owned cutting-edge cars raced at Indy and marketed his achievements with flair, decking himself and his crew out in pajama-like white suits covered with red STP stickers.

Andy Granatelli: A news obituary of auto racing figure Andy Granatelli in the Dec. 30 LATExtra section said he started the Tuneup Masters chain of low-cost garages after a business deal in 1985. The chain was started by Jerry Dres in 1958, and Granatelli had an ownership interest from 1978 to 1986.

The globally broadcast image of the attention-grabbing outfits was "the best thing that ever happened to STP or the speedway," Granatelli said in a recent interview. "To this day it makes the covers of magazines."

Granatelli wrote a 1969 autobiography titled "They Call Me Mr. 500," but he drove the famed speedway just once, crashing in the qualifying rounds in 1948. He broke both shoulders and lost 11 teeth. At the time, he owned a small Chicago garage but was billing himself as Antonio the Great, an Italian rocket-car driver.

Despite the mishap, Granatelli soon was one of the best-known people in the sport.

"He understood better than anyone the spirit and challenge of the Indianapolis 500 and had a remarkable ability to combine innovative technologies with talented race car drivers to make his cars a threat to win at Indianapolis every year," J. Douglas Boles, the speedway's president, said in a statement Sunday.

"Andy leaves a legacy of historic moments that will live forever in Indianapolis 500 lore," Boles said, "including his famous turbine that dominated the 1967 Indianapolis 500, the Lotus 56 of 1968, and giving the great Mario Andretti a kiss on the cheek in Victory Lane after his 1969 win."

The kiss, an exuberant smooch that made the papers worldwide, was classic Granatelli, the late Times racing writer Shav Glick wrote in 2000.

"Granatelli, all 300 pounds of him, ran earsplitting Novis and silent turbine 'Whooshmobiles,' kissed Mario Andretti in the winner's circle, and made STP such a familiar name that when Neil Armtstrong was about to walk on the moon, it was rumored the first thing he might see would be an STP sticker," Glick wrote.

Although the Federal Trade Commission ultimately questioned STP's effectiveness, Granatelli, its president and chief executive, was the ultimate pitchman, handing out STP hats and T-shirts and donning his trademark trenchcoat in its ubiquitous commercials. In less than a decade, he boosted its annual sales from $2 million to $100 million.

The "wondrous campaign represents total involvement of a kind rarely seen in America since the days when peddlers sold their own celery tonic from Conestoga wagons," Sports Illustrated wrote in 1968.

In an Autoweek interview two years ago, Granatelli said the personal touch was sadly missing from today's racing scene.

"It used to be in the 1950s and '60s that you could watch a car go by and tell who the driver was by the way he sat in it, upright or lying down or whatever," Granatelli said. "You can see none of that now, because the car goes by so fast, and the driver is hidden down in that hole. Then the stupid driver gets out of the car, takes his helmet off, puts on a hat and sunglasses, and all you can see is the tip of his nose and his lips. We're supposed to pull for a nose and a set of lips?"

Born March 18, 1923, in Dallas, Anthony Granatelli grew up poor in Chicago. He and his two brothers, Joe and Vince, took to cars naturally, he once told an interviewer.
