Have been using JohnDeere 30w for the Kawasaki engines only because thats what my dealer recommends. Was wondering if I should consider another brand (non synthetic). Was considering Pennzoil.

Some of you are real engine gurus and so I was wondering what brand you recommend and most importantly, WHY that brand??

Thanks

i use Chevron 30w, will also use Mobil 1 10w-30 mixed w/ 15w-50 in the car, and may switch to that blend for mowers.

Why? I have read good VOA (virgin oil analyisis) and UOA ( used oil analyisis) on both these products. There are other oils out there that I have liked results on as well. These are just some that i have used recently with good results.

Go to www.bobistheoilguy.com and read some of his articles, and go to the forum and start to learn, you will be supprised at how interesting it all is.

I get it at my local dealer. Several of the dealers here carry it. Check with other dealers in your area. If I couldn't use Opti I would use Amsoil only.

Saw Man...I did look up that oil website you mentioned....man that stuff went way....over my head....but thanks for the address.

I've never used synthetic so since the mower is 2 years old and way beyond the break in/warranty period I guess I'll give synthetic a try.....being from the old school this will be a new oil experience for me...hah

I stick with the name brand oils, Valvoline, Pennzoil, etc. The detergent packages are better than the quick trip brand. I don't abuse or neglect my engine, so synthetic or other overkill brands don't interest me. I change my oil frequently and regularly which I believe is better than synthetic. No oil can totally remove the dirt and by products from combustion. I prefer an oil change over a synthetic any day.

I have been using JD oil in my equipment, John Deere is using Shell oil , i have used it for 800 hours in my jd 188 and i am using it in all my equipment, the cost isnt much more than other non syn thetic oils, I was a mechanic for 19 years before going in to lawn care full time, i dont see the advantage of synthetics, i always thought we changed oil to remove the dirt and by- products of combustion, but any ways i dont want to start a fight, what ever makes ya happy and works for each other is the name of the game happy cuttin to all

Thats the same opinion the supervisor of the mechanics at my dealer says. This dealer has 6 mechanics and they do a boatload of maintenance on just about every commercial mower in this area so he sees all kinds of situations with our machines. But as you say there are different opinions about sys vs non-syn.

I forgot to mention that the reason i use the jd oil is because it is shell and we used that in our fleet maintenance program with great sucess, and becuase i pick up the oil when getting my filters and other parts from my dealer, one stop does it all, well most of it anyway he he

I always use Mobil 1: Airstream Motorhome, GMC Yukon, Saturn, and all my small engines requiring oil. I change it often, just as you would regular oil. I've not had a problem. I do get a long life out of my equipment, and it always runs like new. I also keep up all the other maintenance, which helps. Don't know if this is good or bad, but it has worked for me for years.

I dont like straight 30 weight oil cause it makes it harder to pull when its' colder out.. I think that the 10w30 is the most versitile weight for power equipment, having been using it for 9 years... BUt have thrown in some amsiol for a while , but could not justify the added expense since I am a nut and change the oil every 25 hours or so with new oil filters. I even have a machine I only put like 10 hours on a month and that gets changed every month regardless.. Thats actually my rule of thumb.... Monthly or sooner if hours permit.... Ohh and I use SHell , just cause its good quality oil and I get it from the same supplier I get my Hastings oil filters from....

10w-30 is an all season oil for cars , because they run during the winter months. When the oil is cold, it will flow like a lighter weight oil until the motor gets to operating temps. Not many mowers see much use when the temps get that low.

In addition, automobile engines run at higher engine speeds and therefore require tighter tolerances for the sake of longevity, whereas most mowers will never see 4000 RPM, so their tolerances are looser. They HAVE to be for pull-start motors, or they would be too tight to start. Therefore a looser tolerance motor requires a thicker blend of oil to cushion the bearings.

Hope that clears things up for y'all.

And for the record, I use 0.75$ el cheepo Dollar Store oil in my equipment, seeing as I change the oil every other month. I gotta 22" Murray 6 horse I have relied on for over 3 years and it was used when I picked it up. Runs great, but in reality it's just a backup in case one of my Toro's go down. One of my Toros is 8 yrs old and uses the same oil with no problems.

Synthetic oil is well and fine to go the distance, but a true green-smith takes care of his equipment, and maintenance is key. If your equipment is seeing a lot of hours between oil changes, then maybe synthetic is the way to go. Change the oil often and they will be there when you need em. We check the oil level before starting them, regardless of if it's been running at all that day or not.

we use Amsoil in all our stuff generally 10w-30 or 10-40 .
I think 10-30s are best cause the engines start a little easier especially in the spring and fall in temps are still quite low I believe is best to have a oil that flows more freely than anything.

30w is the best oil you can use unless you need 10w-30 for colder climates. never anything like 10w-40 in order to make colder temp oils like 10w-40 they use alot more additives than say 30w, the problem is that an air cooled engines run very hot and do not have a very effecient cooling system. the oil in a air cooled motor does alot of the heat transfering. the additives in the winter weight oil break down at hi temps and cause sludge comprimising the oils ability to lubricate. also thinner weight oils can slip past the rings and burn.

Alright all of you 10/30 guys out there here me out.Your choice oil needs to depend on a few variables. First try to use a GOOD Qaulity oil. Your weather conditions Cold weather use 10/30 In hot climate use 20/50 YES 20/50 I've used for years no problems If your going to use regular oil change OFTEN Use syn you can change less often and extend engine life. As long as you chang oil on a reguilar you can't go wrong.
