Can I make my own synthetic oil blend?
I use Rotella Synthetic in my '91 350SD. While, I like it and it lasts a lot longer, I notice more drips and leaks than I did with conventional oil.
QUESTION: Can I mix 1 gal Rotella Synthetic and 1 gal regular Rotella on my next oil change? I would think that this is similar to a blend.
Thoughts?
