Thread: What Oil
02-24-2007, 08:50 PM #1
What type of oil are you guys going to use when you start changing oil?
What are the pros and cons of using a synthetic vs traditional?

I'll be using Mobil 1 long term. Near term at first oil change (probably
at 10 hours) I'll put 10W40W from Castrol or Quaker State.
I think the factory fill is regular oil, Synthetic is so good sometimes
it is not recommended for breaking in a motor. However all my BMW's
and turbo charged Z's came with synthetic as factory fill. BMW
synthentic is Castrol synthentic with a slightly different additive package.
Pro's of syntentic is the oil stays on the parts better for lower startup
wear. Won't break down as easily thermally, hence the longer intervals
between changes. Lower friction gives better performance. Big Trucks
have several studies out showing 1/3% gas mileage gain.

Thanks Tom, I am leaning towards the synthentic also. I am also planning on changing my oil and filter at 10 hrs then will not have to worry about it until the end of the season. It should be pretty much broken in with 10 hrs.
Since you did not give me any cons I guess thats kind of seals it for me.

No cons on synthentic
I have never heard anything negative about syntentic oil performance
other than it costs $5/quart! I sometimes get a case of 6 from
Costco or Walmart sometimes has it in 1 big 5 quart bottle. All the
auto parts stores are real competitive.
I use to broker oil by the truckload and met some good engineers
at Quaker State and Mobil where they make the stuff. When you
get into the physics of how it coats the parts microscopically which
lowers friction and increases life.......you're sold! My BMW X5 is at
155K miles and doesn't use a drop of oil (and of course no blue smoke!)
I'll feel real comfortable that I've done my job by having Mobil 1 in this
high revving baby on a 85degree day out on the big blue!

What does anyone recommend for a good electric fluid extractor?

I don't know if things have changed any, but afew years back I had some engine work done to a snowmobile and the machanic pointed out one downfall to sythetic oil. As the cylinders were off for a couple weeks, sythetic oil runs off leaving them with no protection from the elements. This would be my only concern with a watercraft if it was setting for a couple weeks that the cylinders would have no oil left on them to protect against moisture. If the oils are different now, please let me know, Donald

My question is ... how do we get the oil OUT of the ski before putting in new oil?

i have had good luck with Royal Purple synthetic oil in my race cars.

Oil Extractor and comment on Syn
Donald - wrong info. Synthentic stays on the surfaces a lot better
than original dino oil. That's one reason they are used in extreme
temperature conditions both hot and cold. Most engine wear is
at the startup before the oil pump gets oil to the parts.
Oil Extractor - I love my Tempo Oil Boy
The idiots have discontinued it for some unknown reason.
Several Marine stores still have them on the shelf, my Dad just
got one a couple weeks ago at a West Marine store. You
put a tube down dipstick, pump a few times and it takes over
and sucks that baby dry! Then you have a great cannister to
take to Jiffy Lube to dump.
I really don't like the electric drill ones, had lots of problems with
them overheating and all of a sudden freezing. They also take forever
and you wind up in weird positions trying to hold onto it.
Big boats put permanent 12v pumps onboard connected through
a custom drain plug. Nice but way overkill for this application.
