For our challenge vehicle we’d like to upgrade the piece of heater hose we’ve been using as an oil drain line. I’ve seen a few vendors selling silicone hose rated for oil and gas but I’m not sure what other budget friendly option are out there. What would you use and what vendor has the best price?
I'd use Flyin' Miata, but we're trying to make a living so we're probably not the cheapest option.
Try a heavy truck place. Even better, make friends with someone who works at a heavy truck place and see if he can find you a chunk.
I have a friend that uses a length of garden hose.
I use the silicone stuff from Earl's, but there's an Earl's 20 minutes from me, so i don't have to pay shipping.
I've also bought from ATP in the past, they seemed pretty cheap.
Make friends with someone that works at a hydraulic hose shop. Something like that would be a free left over scrap piece.
Try a middle of nowhere, pallet of tractor hydraulic oil sitting out front NAPA, or one that does a lot of heavy duty truck stuff. They'll probably have some sort of high temp hydraulic hose that would work, being equipped to make any hose a farmer might have needed yesterday on a Saturday morning.

I'd use steel heater hose tubing (free if you're a good scavenger) for the entire run except for a small (2"?) section for expansion and vibration isolation. For that small 2" section, a piece of used heater hose is free and easy to replace. This is what I did on my $2011 N600. However, if you're going for zero maintenance over a long period of time, then I'd go to the local hydraulic supply shop and see what they have in 5/8" ID that is oil resistant. I'd ask if they can give you a 3" chunk to test fit on your oil hose to make sure it'll work. That would be free, and most local shops would be happy to oblige. Make sure you spend some money with them another day and tell all your friends to support your local hydraulic supply places, they're really handy to have around!
If you don't have a hydraulic supply place, most heavy truck and tractor shops stock silicone heater hose, which works for chemical resistance but is pretty sensitive stuff to sharp edges so be careful with it. Heck, most of them will have a chunk of old stuff they'll give you for free if they have a rig they pulled some off of recently.

Keep in mind that it can't be pure silicone, it'll need a liner. If it's just silicone, the oil will weep right through it. The stuff we use has several layers.

Have you ever seen 5/8" ID pure silicone hose on a vehicle? I haven't, but I won't say it's never happened. I've only ever seen the multi-layered stuff for automotive use in that size range. I'm not sure why oil would weep through it, but either way it'd be a silly thing to use...so, good clarification if such a pure silicone hose in that size really exists!

The silicone hose I was looking at was from ATP and has a red inner liner. It was $8 for a foot plus about $8 shipping. I going to try NAPA on Wed to see what they have.
I don't think I've seen 5/8" silicone hose, but I've never gone looking I have seen the weeping when silicone hose is used for things like PCV vent lines, though.
Ours is GATES LOL PLUS LOW PRESSURE LOCK-ON 5/8 HYD HOSE. As described, red inner liner. Price is about the same, we charge $7.20/foot.
Junk yard that has some bigger trucks in it? My local pick and oull has severial vehicals that i would think would have it.

I work at a hydraulic hose shop (Parker) - nothing goes out the door for free!
It's always funny how things change when it's how you put bread on the table...

It must not the Parker store that I do business with
But when you bring in thousands of dollars of work over more than a decade, and refer dozens of new customers to them, they will throw you a few bones now and then.
