Hi guys,
Thanks for the comments. The old truck is working fine apart from the new (last year or so) oil leakage. Until a couple of years ago I doubt if I lost a litre (or quart) over 5,000 miles - usually half of that between oil changes was the norm. Now I get the leaks and loss - not serious yet, but losses over time.
I have also been doing a bit of searching and two products seem to come up a lot. Bars Oil Seal additive and Lucas - I have never used either so it is new to me.
I think I will try some Bars and see what happens. I can live with the leaks for now, though I obviously don't like it. I will post back after trying the product and let you know what I found - if anything.
I have been using the old F250 for winter driving and the Dodge for the rest of the year.
Thanks again for the comments.
