I used the Mobile Delvac Extreme 10W-30 in all my machine servicing earlier this year. The oil ratings are as good as any other top product.

Currently on offer, if you spend $99 you get free shipping. That's $17.50 / gal, great value. I'll stick to the 10W-30 as it covers the cold times here in Northern MI.

That IS a great price if you want synthetic oil... even Walmart wants $32-$42/gal for it.

I see you are using my second favorite transmission fluid, Rotella hydraulic fluid. I may switch entirely to it in as much as winter flowability is as good as the Chevron I use and the cost is less. I gauge everything on how well fluid flows when it's well below freezing.

Only drawback is it's not orange like Chevron.

I did as well, about 60% the cost of Chevron. I wouldn't use it in a hydro but mine are gear drive. For a hydro, I'd stick with Kubota branded 'Valvoline' fluid.
