I've noticed that newer C50 gas tanks have reflective heat shield material underneath the tank (see picture 1). My 2008 doesn't have it. What benefits are in adding heat shields underneaths gas tanks and why older bikes were sold without one?

Thanks!

Psyc0 took my tank off and adjusted my valves here in Pa. on his way from Buffalo to his beautiful home in Florida.

Well, I'll be. Suzuki changed the tank design again. I wonder when that was put in place? Probably their "comeback year" in 2012.

As for the foil? It probably reflects a little heat which keeps the fuel 2* cooler. I wouldn't worry about retrofitting your bike.

Tanks in the picture are 2008 and 2011.

I read a little about this: gas tank shields are somewhat necessary when gas tank is made of materials other than metal, and makes a bit of a difference for high performance engines due to cooler fuel. For C50, probably no feasible performance difference.

I'm pretty sure my 2009 C-50 has the heat shield.
Given that, which oil should I use?

Well, the picture says 2016, but what's 5 years among friends?? :biglaugh:

Good to know about the change in tank design though. VL800 tanks 01-04 will only fit those years, 05-10(?) will only fit those years and (unknown)-present will only fit those years...

Lol, my bad: this is what happens when you take a train instead of riding your motorcycle :) The eBay listing says 2011-2016: https://www.ebay.com/itm/2016-11-16-SUZUKI-VL800-C50-BOULEVARD-OEM-GAS-TANK-FUEL-PETROL-RESERVOIR-CELL/323562034442?_trkparms=aid=111001&algo=REC.SEED&ao=1&asc=20160908105057&meid=c8165f36132142f685d630c7be1a6629&pid=100675&rk=4&rkt=15&sd=333242806298&itm=323562034442&_trksid=p2481888.c100675.m4236&_trkparms=pageci:d2302e90-98e0-11e9-8319-74dbd180dd82|parentrq:9928840516b0a4b7b733d836ffa8e419|iid:1

Fit a heat shield or the tank may explode on a hot day.
I don't see how that could happen unless there is a simultaneous gas leak and exhaust leak in the same vicinity. Gas cap vents excess fuel fumes when gas get warmer. Additionally, I did overfill the gas tank several times to the point where gas was leaking from vent port in the gas cap - I'm still here. Am I just lucky?

If it was a problem there would have been a recall. I use Ocean Potion Oil.
In all fairness, lack of recall doesn’t constitute everything is right. Suzuki, like other vehicle manufacturer, might chose to ignore an issue, even potentially life threatening issues, because the possibility of problems biting them in the ass is minimal.

I did buy a piece of self adhesive heat reflective material for my right saddlebag. It is not strictly necessary, I just want to keep the content of my saddlebag a bit cooler while standing in traffic (pretty much every day in NYC). If I have any of that material left, I might consider installing it on the underside of the tank when I have nothing else to do with my time.

I don't recall hearing of any gas tanks blowing up.
I think it is highly unlikely. There needs to be a combination of fuel and some sort of a spark, either due to friction/electrical issue/exhaust leak. That said, a heat shield won't prevent fuel leak, so no real point in installing it, unless somebody would want to keep the fuel temperature a few degrees lower, and only when motorcycle is standing or moving very slowly.
