Hi All,

 

A couple of months ago I purchased a used 2010 TR-18 pro w/ 150 optimax. I recently had to add some oil and it was recommended to me to use Pennzoil Premium Plus... I know another guy who had a mercury optimax but he had the pro xs.... anyway he uses Mercury DFI oil... is it worth it? It's a little more than twice as much. 

 

I noticed after I added the Pennzoil my next trip out I was getting some smoking out of the motor. Is that normal? I had the boat out a few times prior and I don't recall smoke coming off the motor...I will say the smoke was in the morning. I know thats common on some outboards. I just never recognized it coming out of mine.

 

So 2 questions.

 

1. DFI oil worth it? If so, can I start to use it by just adding some now and eventually move over to just dfi.

2. Has anyone else had issues with the pennzoil premium plus causing your outboard to smoke?

 

TIA

I made the switch to Pennzoil a few months ago and no issues at all. Same smoke as with the Merc oil.

Were you using the DFI synthetic? 

The lubricating properties are compatible with the engine. The DFI oil has additives for carbon as well as other things that may foul the engine. So, the Penzoil will work but it may not be the best option

What would you suggest as being the best option? I don't mind spending more money to prolong the life of my motor.

I use DFI I buy it from domo online who has the best pricing on the net. Also use the mercury fuel additives on every fill up.

What does the owners manual say to use? Can't go wrong by following the manual.
