    The verdict is in, synthetic oil is the best

    Synthetic or conventional oil? The verdict is finally in
    I’m pretty sure the dinosaurs died out when they stopped gathering food and started having meetings to discuss gathering food

    A bookshop is one of the only pieces of evidence we have that people are still thinking

    There is no doubt that on paper synthetic oil is better than mineral and I would never use anything else on my RRS. However I have used it in one of my older cars and the oil went through it like a dose of salts. Oil pressure was lower, and it was being burned - I guess that even though the engine was new having recently being completely rebuild the oil just seemed to slowly disappear and the engine just did not sound right - mineral oil works great.

    So I guess it is great on some engines but not so on others.

    I emailed Penrite and asked the question which one they recommended, never got an answer. I tried the fully synthetic HPR5 but didn't like how it came out too clean so went back to HPR5 diesel. My understanding was older engines were designed to have zinc and diesel oils where higher in detergent to help remove contaminants and should get "dirty". The website recommends HPR5 diesel for the TD5.
