I just picked up a new bottle of Bel-Ray filter oil and when I went to use it it poured like molasses , I had a old bottle with a little left and it was a lot thinner and it was easy to get the oil throughout the filter, The thick stuff in the new bottle sucks to get evenly through the filter. I don't know if they changed their formula or just had a bad batch. I've been using it for years and this is the first time I had a bottle like this.
Has anyone else had this problem?

Sounds like a bad batch, I’ve been using it for over ten years and never had anything like that.

It's the best filter oil, in my opinion. It is usually pretty thin when it comes out, but gets really tacky and doesn't settle out like all the others seem to do (I'm talking over a period of months, on say a street DRZ400...) You may have got a bad batch, or possibly it's been sitting on the shelf a LONG time...

for me... only air filter oil I use is Maxima. I don't think I'm alone.

Has a similar issue and wondered if they changed the formula too, asked the dealer and they had no idea. Not planning on changing brands but it does take some effort to work it through especially if it is cold.

Bel-Ray filter oil is just very thick, which is also what makes it great. My application preference is after cleaning the filter in a solvent, while it is still damp apply the oil. The residual solvent will help spread the oil, but there isn’t so much it creates a mess.

Been using it for 20ish years and its always been on the thicker side. Love it in the summer due to it NOT being too runny. It doesn't get real cold down here in the south for long but if/when it does I switch over to Maxima, which in the summer is too thin for my liking. They both do a great job at keeping clean air entering the engine.

I have always put a tiny amount of gas in mine just to thin it out a little.

Been using it for 35+ years. Tried others and always came back to ole reliable. It's always been on the thicker side but I have not had any approach the molasses level of viscosity. If I had one that bad, I'd add a little odorless mineral spirits to thin it out. In the winter, I will set the bottle in the sun for a bit to warm it up and get things flowing.

There is a problem with it. We've had a few bottles replaced and some of the new was still incorrect.

Will mineral spirits evaporate?

Evaporate from the bottle like too soon? Don't think so. Think the carrier agent that is in the oil already is mineral spirits or something similar.

Evaporate from the filter after applying as you want? Yes, it will.

Great yes to evaporate fast after application.

The best thinner is mineral spirits.

I have the Twin Air tubs and occasionally have to pour a little mineral spirits in to dilute the goo. Works great and makes the Bel Ray go a long ways.

Maxima FFT!

Goes on thin and the carrier evaporates in like 15-20min and sets up nice!

Thanks for the responses guys! I bought the bottle from a busy shop so I’m sure it’s new stock. The old bottle which was fine that I used up first was from last year so I doubt the new bottle is so thick from being old stock.

I used to use Maxima FFT , it was good but a little too thin, it took longer to set up.

Yep they had a bad batch I think last summer. I know they sent my dealer a case to replace the ones that were bad.

Hey guys, as Spooner said, last summer we did have a funky batch. Please email me with a picture of the rear label to confirm the batch number and I'll get you a replacement bottle. cody.wolf@calumetspecialty.com
