So he ordered some from a distributor that we found here locally and they sent it in Quarts, but now it says "New Formula" on the front, and it says synthetic...the old bottles didn't say this... His car has the original rubber seals in the system, and we don't want them to deteriorate. Do you know if this oil is still vegetable based or not, and if it is safe to use in his car? Thanks for any help/advice!
All brake fluid is synthetic, LMA included. Boy this synthetic causes leaks thing sure has turned into billboard myth material. LMA Vegetable based? Never heard that one before. I'm sure the LMA is still fine to use, but I can't necessarily say what is improved about this iteration.
