I thought I'd post up not to spark the dino vs. synthetic debate but to share my experience with synthetics. My 2h has approximately 300,000km. on it. First I added seafoam to the crankcase to clean it up as best as it could then I drove around for about an hour. I received a case of royal purple from a local promo rep as he is trying to push royal purple on biodiesel trucks. Took the oil and my new filter to toyota and had them do the work. The oil that came out of the pan was so sludgy that it barely made it through the filter screen on their oil barrel. After some patience (had to drain the oil little by little) the plug and gasket were were put back on with the filter and royal purple was added.
My impressions:
The truck is a lot smoother, especially at lower rpms, but seems to drive a lot smoother as well. The idle instantly went up a little higher as well. It's been 4 days and I have no leaks. My synopsis is that though expensive I think the synthetics are definatley worth it- even on an old engine. We are going to do continued oil analysis on my truck so I'll post up the results.
By the way, i have no affiliations with any of the products I used.
cheers,
David
