Has anyone used Pennzoil Multi purpose 2 cycle oil yet? I have almost given up trying to find good ole LB oil. And have tried all the Multi ratio Pro mix and what have ya. So I thought I,d try the Pennzoil which is pretty easy to find around here. It seems to run a lot better on the Pennzoil than the Pro Mix I had been using. One thing I do miss is the puff of blue smoke when you first start it up. The 10201 just won,t do it. My 10424 dura force would always puff a bit at first start. I always thought it was the LB oil.

I haven't tried the Pennzoil, but I do use Valvoline multi-purpose 2-cycle oil. It's labeled as ashless with a TC-W3 rating. A.C.E. hardware does sell Lawn-Boy oil. You'll find everybody has their favorite oil, some liking the synthetics over regular.

Never tried it, but my personal opinion is any quality 2 stroke will be about the same. Some are even master-manufactured by the same parent company, and re-packaged as another brand, so "ECHO" 2 stroke may be identical to "Poulan" 2 stroke. Obviously, a small Chainsaw and Trimmer manufacturer is not going to set up an Oil refinery just to sell oil. They buy it from a repackager. Thus, I don't stress much over brand X over brand Y. However, I do compare Synthetic to Regular Oil. Those birds are two very different molecular animals.

I used to do only "Lawnboy Ashless Oil" mixed exactly at 32:1 and still had carbon buildup on my exhaust ports. Tried a lot of different oils including synthetic, and the best i found is Royal Purple 2 stroke Synthetic. Since switching to it, no issues. I run it a tad lean. 40:1. I have run it at 32:1. No difference either way. Your comfort level. I now prefer synthetic and like "Royal Purple" the best. It's available at Walmart, Amazon, etc. I have no affiliation with the company. Just a happy consumer.





If you REALLY have to have the original Lawnboy cans, you can get them from online ordering like here:

Pe Oils & Lubricants : Lawnboy Generation Ii 2-Cycle Oil

As posted above, someone manufactures this FOR LawnBoy. You can probably get the exact same oil from someone else, but WHICH BRAND is the issue. Someone that knows LawnBoy and their 3rd party suppliers could tell you.

Both the ACE and Tru-Value local franchise hardware stores here still stock Lawnboy 2-cycle oil, although I suspect brands such as Poulan and Stihl are pretty-near identical. I see in the link above, Pe Oils is selling "Generation II" oil. Bear in mind, that Lawnboy oil is now "Generation III".

The Penzoil you describe works well in Lawnboys and about everything else for that matter. The Valvoline multipurpose is very good as well.

Sounds good. And blue smoke at cold startup. Are you happy with it so far? If you are , are you going to keep using the Pennz-Multi-oil? If you like it and you keep using it, keep us updated as to exhaust port ash buildup and plug fouling, etc. How is the price compared to the others?

Just wondering it keeps coming up that people are having trouble with carbon buildup in the ports using Lawn Boy oil at 32to1. I do not and have not any carbon build up on any of my Lawn Boy mowers 1970 and up that I have run at 32to1 using LB oil. I only have LB mowers and mowing since 1965. Are your carbs adjusted properly? Do you have leaky seals or gaskets causing motor to run poorly? Is your ignition operating up to proper voltage and are you using the correct good condition spark plug that is properly gaped for the type of ignition on the mower? Have you been cleaning your air filter when dirty? Are your reeds sealing well? Does the engine have poor compression? Any of these could cause carbon to form. Lawn Boy oil gets blamed for carbon buildup, when the cause is a mechanical defect or lack of maintenance.

Yep, The old Lawn Boy has,nt run this good in years, so I,m sticking with it. I mix it at 32:1. I,m going to try it in my weed eater next. The price is $3.69 for a 16oz. bottle which I think is pretty fair. I,ll keep ya posted on port build up and plug fouling.

Exactly...
I have three machines that run 16:1 with SAE 30W...I have seen more carbon build up in Duraforce engines.

The puff at start up is a symptom of a leaking needle and seat. As the motor and exhaust heat up to operating temperature the excess fuel and oil vaporize and may not be as visible if visible at all. You may also see the result of carbon forming in the ports. Any smoke is excess oil that will cause carbon formation in ring grooves, ports, top of piston,and top of cyl. ,and in muffler, also on the spark plug electrode. This gets back to proper maintenance and repairs. A dirty air filter restricts air flow making the mixture richer, more fuel with more oil, leading to carbon showing up in the ports. Carbon build up sticks the rings, lowering compression resulting in a poor running motor using more fuel and making more carbon.

To each his own on 2-stoke oil, really any oil you run through a lawnboy is going to work well given the operating Rpm and HP out put. I have been snowmobiling for over 20 years, since most current snowmobiles have power valves that tend to gum up and cause running issues. Ash less and oils that do not build up carbon is a must. I have used Blue Marble for 10 years in all of my 2 stokes snowmobiles from a 600 to 1000 cc. I do not have to clean the power valves only inspect them. I would think the issue of plugging a muffler with carbon should be greatly reduced using an oil like blue marble.

I have been using Pennzoil Full Synthetic OUTBOARD MOTOR oil in my Lawnboy mower, Toro S-200 snowblower, weedwacker, and gas leaf blower for 10+ years with no issues whatsoever. Most outboards are water cooled to about 140 degrees, so oil formulas need less temp to burn off port deposits. I buy it at Menards for about $28 a gallon. Pretty cheap for full synthetic and its 100% biodegradable to boot.

Actually It's been said it before with today's advances in oil technology compared to the 80's almost any 2 stroke oil will work!!
