Was in at Wal Mart last night and noticed that they are selling Rotella T 15W40 for $51 a bucket. They also have a 9.5 L jug but I don't remember the price. Its good stuff in the Tercel - for slowing down its consumption of oil. I used it once in the Safari and it seemed to be as good as the Delo 400. Anybody else using it in their diesel?
