Not a statistical anomaly but the Jordan 198 used Elf fuel and lubricants despite being sponsored by Repsol.

Repsol didn't pay enough.

I suggest that was soley a decision made by the engine supplier and their lubricants partner.

This is also true for Arrows A20 and A21.

A lot of that would have to do with Frank Williams.
He had deep pockets and very short arms.

And, as with most cumulative records, a lot to do with less races per year back in the day. Drivers don't stick around on rubbish teams, which Williams have been for most of the 18+ race per year era.
Mansell is their most capped driver with 95 starts. He drove 6 full years plus a few races. That would would be 130+ races these days.
