Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

For every new engine I ever purchase, whether in a new car or a lawnmower I change the oil after just a few hours of use.  I learned to do this because a new  engine wears in and creates small metal particles that cause excess wear if they are not removed from the engine, and even in new cars with oil filters the filter is limited in how small the particles it can trap.  In the case of my New Honda GX 270 engine that powers my Honda Snowblower, I ran the machine for about 2 hours, then drained and refilled the engine with 100% synthetic oil.  When the oil was visible in the drain pan it was grey in color from the large quantity of metal wear particles suspended in the oil.   I will probably wait another 4 to 6 hours of operation before doing another oil change.   Considering that the expensive new engine only requires a little more than 1 quart of oil, and it has no oil filter, it seems a prudent investment to add these very early oil changes to the maintenance regimen of a new engine.   Incidentally, Honda suggests the first change after 20 hours.  Based on the evidence of the metal in the oil, I would suggest that is far too long to wait for that initial oil change.  

I'm curious how others feel about this.

Synthetic Oil has many advantages over petroleum, not thinkening is but one.  Dino oil breaks down from heat and creates sludge in an engine.  I have cars in the family with 300K on them and oil that is clear, you can't do that for 10,000 miles with the Dino oil.   Toyota had a problem a few years back with sludge clogging up their engines, not one case was seen in engines that used 100% sythetic oil.  The first jet aircraft engines the nazi's built in WW2 had to be torn down and rebuilt after something like 9 hours because the oil would solidify from the heat.  Amsoil, the first automotive oil to be sold that was 100% synthetic was begun by a man who was a pilot, and understood that advantage.   The advantages are easily worth the extra few bucks, especially when the engine only holds about 1 quart.  I always keep the machines I buy for a long time.  If I leased cars, then OK maybe it'd make sense to do whatever is cheap, and minimum and let the next victim deal with the problems, but that's never been me.

Thanks for the fair warning - I will neither buy a used car nor snowblower from you.

Synthetic oil makes my engine run at lower dB.  Noticed the difference after I changed from a conventional oil to synthetic.  My neighbors will appreciate this $3 upgrade and I feel better.

  Yes Guys, Always Follow The Owners Manual !

Sorry mikiwest,  But Oil Changes are recommended by Honda to NOT EXCEED 20 hours initially, nothing in the Honda Owners Manual suggests the oil may not be changed more frequently if one is enlightened enough to do so.  Oh, and don't take My word for the metal wear particles in the engines oil, just look at the oil and see them for yourself.  mikiwest may think this to be as complex as Rocket Science, but it's actually all pretty simple stuff.

The Owners Manual IS always right !  It requires the oil be changed once before 20 hours have been exceeded, I did that, I changed the engine oil after 2 hours.  How is that not following the owners manual ?  Do you understand any of this ?  If I decide to change the oil 20 times before the 20 hours how would that not be following the owners manual ?  Why do you make these comments ?

The HONDA owners manual tells the proper weight and API classification for the oil, How does using that weight and classification conflict with the owners manual if the motor oil is synthetic instead of the cheaper dino oil ?  Where in the Owners Manual does it prohibit using synthetic oil ?  So this is yet Another Bogus Statement  (BS) by mikiwest ?

What is wrong with you? I have been on this site for a few months while shopping for a snow blower. You have some good knowledge on these machines, but your attitude and ignorance make for some ruined forums. There are people like me who come to this site for knowledge not $#%* talking. If your going to talk $#%* all the time do it on facebook or something. Don't give New Yorkers a bad name. Change the oil whenever you want. It's your machine.

Nothing I did or suggest is against anything in the owners manual.  If you imagine that to be the case provide the OM entry, and I will respond.

Why ? Because You Would NEVER Want To Buy a Machine From someone who followed the Owners manual and even exceeded its minimum requirements ?  I would only sell something used that I needed to dispose of to someone wise enough to appreciate it.  So you are correct, You would not buy a car or snowblower from me, of that I am certain.

Hi Chxbeachva,

You are right on.  Keep us true!
