Amsiol or Delo400?

[Archer]

I Bought a 99psd new and have always run delo in it, I've been reading about the posts from Amsiol users and can't decide if I should spend the extra money for the synthetic. What does the forum think?

I think synthetic is great for the winter months. I went to Retella 5w-40 and it made a huge difference. Easier starts and the engine seemed to be quieter. Its up to you if you think the extra money for the synthetic is worth it. Just make sure its diesel rated oil.
