Romain Grosjean says he is retaining the backing of the French oil company Total.
While the Frenchman is staying at Lotus next year, it was believed the arrival of Mercedes power and Petronas fuel could pose trouble for Grosjean.
When asked about that, Grosjean said in Abu Dhabi: "Total is my personal sponsor.
"Due to the transition to Mercedes engines their (Total’s) logo will no longer be on the car, but Total will continue to support me personally," he is quoted by f1news.ru.
