Fixes 2 issues: Has ZDDP and leak stop
i bought this because it has ZDDP, which my old engines require, and it has a seal additive to help reduce leaks which can be common in old engines. So this is a great product because it claims to deal with two issues. I will continue to buy this.

Really thick - have to dilute it with oil to get it all out of the bottle
Not sure if this will help extend the life of the engine. But if it does what it says it does then hopefully it will .The one slight comment I have to make, is that it's very thick, which makes it difficult to pour it out through a funnel and into the engine. I actually worried if this might even fill up many of those small passageways in the engine and actually cause oil starvation until it's fully mixed in .I ended up pouring it in small amounts, and then adding engine oil into the bottle and giving it all a good shake. Did this 5 or 6 times until the bottle could be emptied easily.The engine seems to misfire slightly on starting now, which it didn't do before I put this stuff in. But of course that could be just coincidence.
