Default Synthetic or synthetic blend.

I know there has has been tons of discussions about yamalube vs pennzoil and other brands. Rather then sift thru hundreds of threads I figured I will get an answer quicker by creating a new thread.
Very simple question- I have a 2006 300hpdi that always burned yamalube. I found a great deal on pennzoil Premium plus tcw3 synthetic blend. Is this OK or should I go with full synthetic? Why and what are the pros and cons.

Due to insane pricing yamalube is no longer an option.

Thanks in advance.

Yes. Do a search for the why and the pros and cons.

the penzoil is a great oil. I burn it in my 250 DI's and my yamaha 90. Everyone seems to have much better results with the penzoil synthetic blend then the yamalube

Do you use pennzoil semi syn?

As soon as I place my order I will post it here. I just want to ensure I get my order in before sharing with the world. Otherwise I may shoot myself in the foot. I also need to make sure theres no gotchas on the shipping costs.

The Walmart brand oil, which IMO is decent oil, is $11.82/gal.

I do use the semi-synthetic. I was able to buy about 20 gallons last year at Sam's Club for about $7.50 a gallon. I now wish I had bought more. They had several pallets of it.

I've run nothing but the PZ synthetic blend for the past 4 years. It burns much cleaner than YL and it reduced the need for new plugs, cleaning the O2 sensor, and decarbing the motor from 3x a year down to 1x.

I think the question is: PZ semi v. full synthetic, which is better? I don't know. All I can say is that I use the semi synthetic because its cheaper then the full synthetic. Not sure what the difference would be. As everyone has said and agree----PZ semi or the synthetic, will produce less ash and therefore less smoke then the YL. It also will result in less carbon build up and leave less on your plugs. This has now become fact for me. I switched about 6 months ago, because I was gettin a great price on barrelled YL. But then saw my plugs getting fouled early and I switched for that reason. I am convinced after pulling those plugs many times over, that they will last longer and the engine will have less carbon buildup then with YL. Also, use ring free for maintaining it.

the full synthetic is better, but not worth the extra money IMO. the semi synthetic is a very good oil

I've got a new to me boat coming this week. It's got a 2004 200 HPDI on it, and the oil tank is about 1/2 full of YL. If I plan to run the PZ, should I wait to burn all of the YL (i.e., until the tank is nearly empty) and then start fresh with PZ, or is it ok to mix?

Sorry to hijack!

it is supposed to be ok to mix any tcw3. I still prefer to get the old oil level as low as possible and then switch. Might even be worth cleaning the tank out to make sure it doesnt have any water or dirt contamination and start fresh sicne you just got the boat

This might be a silly question, but what do I use to clean the tank? Thanks!

I fouled mine up a few years ago by mixing Evinrude oil in my oil tank with my Suzuki Oil. It turned some to jello and plugged the screen - my oil flow sensor shut the motor down to 1000 rpms. Had to mix some oil in the tank and idle home. Dealer told me never mix oils again. Changed out all the lines and started over with a clean tank.

So did you replace the entire oil tank or just clean it?
