how long is the lubricating oil replacement cycle

I believe I pay about $35 for a gallon of GN 4 and an oem filter

I pay about $30.00 for a gallon of full synthetic Shell Rotella and a OEM Honda filter.

Those numbers make sense fer 'merican prices.

What is the oil grade of the Shell Rotella? Walmart?

I suspect he's using Rotella T6 5w-40. It's the only full synthetic Rotella that meets the JASO-MA spec required by Honda. They also make a non-synth version (T4) in 15w-40 that meets the spec.

I usually buy the gallon jug of T6 at Walmart for around $21-$22.

Yes sir. Been using Rotella T6 for many years. Meets ALL the standards for ALL engines at 1/3 the price. I use T4 for break in.
