" As you are aware we have recently been experiencing problems with inconsistent supply of Vortex 98. Unfortunately, BP have advised us again that due to refinery related issues that they are unlikely to be able to supply any further V98 until at least next Wednesday. Despite Caltex having received a small release of product ex Mobil today, Caltex and alternate supply points have now stocked out. "
" As a base U98 & V98 are exactly the same product with the exact same octane rating, the only variance is the cleaning agents that caltex add to make it a different product, this doesnt change the octane rating.So if you got a batch of low V98 then the same batch of U98 would be low as well "
