Red Bull Formula 1 chief Christian Horner has called on the FIA to issue a technical directive to clamp down on teams burning oil as fuel෴ during qualifying, claiming there are “still loopholes” that are being exploited.

The FIA moved last year to tighten the regulations surrounding the for⛎bidden burning of oil as fuel to try and aid consumption and increase ho൲rsepower, with tighter restrictions being imposed for the 2018 season.

A technical directive was issued by the FIA last week to enforce parity between the engines used by factory teams and those supplied to its customers, but Horner felt that oil burn was a more important area that needed focusinꦛg on.

“I think thꦰe other technical directives that have been interesting is obviously the amount of𝓰 oil consumption and the way that that’s used this year,” Horner said.

“Ideally we’d like to see that go further because it still doesn’t ultimately deal with qualifying. I think it contains the race, but still 💛there are windows of opportunity in qualifying that we’d like to see further closed dow✃n.

“It’s mainly between the engine manufacturers and probably worth speaking to Renault about, but we feel there are still loopholes in qual♏ifying that need tidying up regarding consumption.

“We felt that it’s been dealt with in the race, but of course if you were to find a way of using lubricants in a different way in qualifℱying, it offers a significant performance increase.

“We would like to🧸 see belt aไnd braces that closed down.”

In order to curb the burning of oil as fuel, thꦛe FIA issued a technical directive ahead of last September’s Italಌian Grand Prix𒊎, reducing the oil consumption of new powerܫ unit elements from 1.2 litres per 100 km to 0.9 litres.
