New bottle of SI-1 has an unfamiliar bluish tint

[mkosem]

I recently refreshed my fuel additive stocks with a fresh batch of Redline SI-1 and found, upon opening the package, a slightly unfamiliar colored liquid in the bottles that arrived. I've been using this product for years, and know it to have a dark amber color, but the new stuff that arrived seems to have some additional bluish tint to it (akin to a 2-cycle oil). Even after giving it a good shake (in case it had separated somehow, which would also be unfamiliar), the color still looks a bit different. Has anyone else noticed the same or heard any chatter about this product getting reformulated?

Does Redline have an 800# to call and ask questions?
If you're concerned about the product, don't use it!

Mine has always been bright red. But I haven't bought any in about a year.

Recently picked some up at a store and it was red, are the seals still intact under the cap?
Its likely just a different batch with the dye mixture off a bit.

Certain dyes can sometimes have a strange iridescent look to them. I've gotten washer fluid that looks like that. If the seal is still intact, I wouldn't worry too much.

Call Red Line if it bothers you.

The seal was perfectly in-tact. I'll contact Red Line for additional info.

They change all the time. That's likely why they have a range in their MSDS.

SI-1 has been a product for over 20 years. I'm pretty sure at one time it used a different type of detergent. I even remember years ago it was very much red. They could easily just put in a different set of dyes or a fairly simple modification.

Seems like it's probably fine. I just think the color is a bit different than I'm used to it being. I've been using it without any issues so far. I didn't expect any issues really, since Redline makes awesome stuff. I was just curious if they had changed it.

Redline's response was:

Thank you for contacting Red Line Oil, I just checked the current batch and is has a dark amber appearance. That product is not dyed, so it’s appearance can vary between one batch and another due to the difference in the appearance of the components used.

I started thinking about it, and you might be noticing something coming from the bottle itself. They actually have two different bottle types. Most of their bottles are a stiffer plastic with "#7 V" on the bottom. A few of theme are PETE (#1) which is a noticeably softer material and tends to give off a bluish tinge.
