Do Not Use Synthetic Engine Oil

This is the first start of my New Lawn Tractor

This is how I ballance mower blades

This video is about an oil recommendation for a specific air cooled lawn tractor engine only during its break-in period. This video is not about any other engines or any engine oil brands.

I've put synthetic in everything from cars trucks motorcycles Small engines etc and it's always worked fine for me.

I had a 1981 corvette. I built the engine myself and only used synthetic motor oil. Over 40, 000 miles of extremely hard driving, driving that would crystallize a new set of brake pads in a couple of hours. When I took the motor apart it was as clean as the day I put it together. Bearing clearance unchanged. I only use synthetic oil, that sold me.

As a master engine and compressor technician I will give it to you simple. Do not use synthetic lubricates while breaking in an engine " seating the rings" but after that it is preferred in almost every situation. The reason is simple. synthetic oils are very good at what they do so you tend to see incorrect crosshatching take while using them to cut the rings. this causes a glazed cylinder and poor oil retention after a few hours of the breaking in. Sometimes the glazing is so bad re-ringing is required. Use petroleum oil for break in and synthetic from then on out.

I’ve used 100% synthetic from new to 300k plus. Absolutely ZERO problems.
Mobil Extended Performance is awesome!

I'm 70 years old, I spent 4 years at GMAD (General Motors Assembly Division), 1978-1982, I spent 15 years as a chev mechanic at an Atlanta Area dealership, also spent 2 years at a phone center processing and ok'ing under 600.00 auto repairs for a Automotive Protection company, I've researched synthetic oil for over 10 years and have used either Mobil 1 or Amsoil 100% synthetic motor oil since 1978. So I've used synthetic motor oil for 44 years without 1 single oil related failure. So I doubt that you'll have much luck changing my mind. I don't have a tractor.

There has been many study’s on this. Synthetic works so well that the manufacturers want you to break in with conventional because it allows wear. Synthetic slows the wear down so much it takes much longer for break in.

I've used synthetic oil in all my engines for the last 20+ years with no problems.

What that tells me is that synthetic oil is far superior to conventional oils. If the engine won't "break in" with synthetic then it isn't wearing any of the engine parts. An engine "break in' is the wearing of the cylinder walls and rings also called "seating" the rings. I use synthetic oil in everything I own and have for many years. I change my own oil and ship a sample off to Blackstone Labs to have it analyzed for wear metals and contaminants. 130, 000 miles on my Town and Country, 75, 000 miles on my wife's Honda CR-V, 19, 000 miles on my Harley Davidson and every oil analyzation has come back indicating no wearing metals or contamination. My Harley and CR-V came from the factory with synthetic and will see nothing different as long as I own them. One other thing, I rather think Kohler lawn tractor engines are not manufactured to the same specifications as todays automotive and motorcycle engines.

Reason manufacturers say dont use synthetic oil is it makes your engine last too-long bad for repeat. Business

[danlees]

I use synthetic oil in everything (cars, trucks, tractors, log splitter, etc.) and have for 30 years with NO problems.

[cybergrindin]

365000 miles on my Toyota. Never had nothing but full synthetic Mobil 1 in your hands. Runs like new

[larrybarrios]

I've used mobil-1 synthetic since 1974 approximately in all my vehicles including 2 stroke engines. Never ever have i had a problem

Steve, get a hot plate. Find two pans you don't care about. Pour synthetic in one and conventional in the other. Apply heavy heat to both until they evaporate but not catch on fire. The synthetic will almost completely evaporate other than the additives and the conventional will leave behind sludge. In modern engines that sludge builds up over time and restricts engine seals from conditioners in the oil that keep them from cracking and leaking oil.

Need a reference for my rant? My entire family attended a college just northwest of Houston that has one of, if not the best petroleum engineering programs in the world. You have no idea what you are talking about and are going off of what small engine manuals are saying. In every conceivable metric, synthetics have a higher specific heat capacity, have better viscous characteristics, and protect better before the additive package is even considered. Honda, Toyota, and many other mainstream manufacturers are all calling for synthetic from day 1. They want to require it for two purposes. 1) It protects the engine better and reduces the amount of warranty claims. This reduces their liabilities. 2) People that cheap out can be denied warranty claims, reducing their liabilities.

There's a thousand tests on Youtube regarding the capabilities of synthetic vs conventional, but God bless you for reading a paperback manual. "Here's your sign..." - Bill Engvall

I’m a Koehler generator tech, all we use is synthetic lol

[sandman]

Synthetic oil is much better than natural oil in every case. Synthetic oil will break down less and has a much tighter bell-shaped curve. My engines last forever. I only use synthetic oil.

Been using mobile one for at least 25 years, no engine issues from the oil, engine SO clean inside

[Myvintageiron]

Used Mobil 1 in everything zero problems in the last 15 years

[rumart]

I have used synthetic oil for my Toyota Camry 2009 since day one and it's been with me for 12 wonderful years. I haven't experienced any problem with its engine. It has been running like new. No leakage, no unusual engine noise, and no deviation from its usual maintenance.

My 17 yr old daughter had a 78 buick. Engine locked and stalled her on highway. Called me to pick her up . Got to her location checked oil, nothing on stick, I had one quart of mobil synthetic in truck. I dumped that in and started the vehicle. Without a problem, we drove back to home, i changed oil and filter complete. Drove car for two years and sold it. Car is still is on the road as i know, I'm sold on synthetic oil for all my engines large and small.

I've been running Mobil 1 synthetic in every car and motorcycle I've owned since 1991, and my dad has been using it since the late '70s. We're both big believers in how great it is, and the incredibly low amount of wear and 'gunk' in the engine is impressive. When you see an engine with 150, 000 + miles on it, and the cams barely have wear marks, and there's no crap in the valve covers, even in the corners, it shows how great it works.
