Gear Lube

1978 Mercruiser 898 w #1 Drive
Last year when I changed the oil in my lower unit, I purchased Mercury brand "High Performance Gear Lube +". I had a small amount left in the bottle, so when I decided to do it this year, I sent the wife out with the old bottle to one of the "Big Brand" stores. When she returned, they had sold her Quicksilver brand, "High Performance Gear Lube". I know that they are the same company, however, is it the same oil? I know you are not supposed to mix "Premium" with "High performance" but the lack of the "+" has me a bit confused. Thanks for the help.

If it's green, it's the right stuff.
That's Marketing for you.

No they are not the same product.
The Hi Performance is green and is newer than the Premium Blend which is a natural oil color. The Premium Blend is what was originally used in the 78 drives.
While it is fine to use in your drive, the Hi Performance is a synthetic, the Premium Blend is NOT. Don't mix them.

Guys,
Thanks for the response. Here's question that I forgot to ask in the thread. Can the Mercury "high perforamnce gear lube +" be mixed with the quicksilver "high perfomance gear lube"? I'm not aware if the Mercury product has some other additive that would not be compatable with the Quicksilver. Hence the "+". Thanks again

Re: Gear Lube

Quicksilver is a Merc name. Not sure why they ever did the 2 name thing, but the Hi Performance and The HP+ can be mixed together.

Re: Gear Lube

ASAIK Mercury/mercruiser sell their maintenance products under the Mercruiser and the Quicksilver brand - they are the same just different labeled.

I have used both Mercruiser oil filters (black) and Quicksilver oil filters (white) but acc to my mercruiser dealer there is no diff. just 2 brands of the same product

Thanks to one and all. I didn't want to have a headache over this later on.

Re: Gear Lube

What I would like to know is do you have to use the Mercruiser/Quicksilver brand oils for the drive. I see many oils that state they can be used in Mercruiser drives and not void the warranty. I had a shaft seal go bad and drained all my drive oil out of the reservior and just wondering if I can refill with something other than the Mercruiser stuff
