## What is Oilmanac?

Oilmanac is a maintenance manager and service log for all your machines with small engines.  It keeps all your maintenance data in one convenient place - on your iPhone, iPad, or both. No need to dig out the user manual and page through it every year to perform routine maintenance on your machine. Pull up the machine in Oilmanac, and all the information you need to perform the maintenance is immediately available. Once the maintenance is completed, you can easily record all the services you performed in the Service Log tab.  

Enter your model specifications and maintenance recommendations for each machine from your user manual, or download them from the user database if available. A wide variety of machine types are available, including lawn mowers, lawn edgers, leaf blowers, yard vacuums, weed trimmers, hedge trimmers, tillers, power washers, water pumps, augers, chainsaws, log splitters, generators, snow blowers, outboard motors, personal water craft, all terrain vehicles, and snowmobiles. Available services are tailored to the specific machine, including oil and oil filter change, spark plug change, air filter clean and change, transmission/gear oil change for self propelled machines, grease, and others.

Additional features:
∙ Automatically download model specifications and maintenance recommendations from the user database
∙ Complete service record for all your machines 
∙ Create shopping lists for material needed for service: oil, filters, spark plugs and more
∙ Set reminders when service is due for each machine, or schedule annually

### 5/5 — Great app for tracking machine maintenance

*2024-08-03, version 1.7.1*

My owners manual for my zero turn lawnmower, didn’t give part numbers for filters and various other consumables. It took considerable research to find that information, but once I had it I entered the information into this app. The time spent was well worth the effort. The data seamlessly synchronizes into iCloud and all of my devices.

### 1/5 — No customer service response

*2023-02-14, version 1.4.4*

Bought app and it’s not what I read.  Tried to get help but no response.  Asked again and want to cancel and reverse charge and no response.  I would not recommend it.

### 5/5 — Great app! Great value for the price.

*2022-04-23, version 1.3.3*

For an inexpensive app it delivers way beyond expectations! I’m happy to work through the minor things I would want to have for the rest of what this app delivers not to mention how responsive the developer has been with great suggestions for using it outside the way it was originally intended.

### 3/5 — Very good app but needs Serious Tweaking!

*2022-04-07, version 1.3.3*

This is a really necessary app for the conscientious machine owner and a great idea.  
For the most part it is very practical and applicable.  However, it lacks user directions so is not very user friendly and is missing some important data collection categories for some parts that are provided for others; eg. suggested spark plug gaps for some machinery but not others; model and serial number spaces for some but only model for others.  Overall very useful and appreciated.

### 4/5 — Good but needs additional maintenance field

*2022-01-04, version 1.3.2*

Unable to add or track other maintenance such as blades. Lots of miscellaneous parts are helpful to track. Snow blower paddles and scraper blades for example. Currently adding to notes but it should be maintenance item

### 5/5 — General

*2021-11-03, version 1.3*

I asked for my company equipment brands to be added and in less than hour maybe two app had everything I asked for and for other equipment in fleet they said they would make happen and to add that much takes time so very pleased to use this app thanks to you and your team

### 4/5 — Good app. Needs a few things

*2020-08-31, version 1.2*

Just got the app and I really like it for the most part.  There is a lot of good thought into maintenance intervals and storing part numbers. 

This has been mentioned but I will also say it. We need a way to manually add some categories. I own some classic tractors a bobcat and multiple trailers that I would like to track on this. I looked in the + to add and I only see fixed categories. I don’t see where my Bobcat or a tractor fits in. I can put it under mowers but that’s not what they are. 

Like I said. Good app just as some customization for some of us who live outside the norm.

### 3/5 — One improvement to make it perfect

*2020-06-27*

Overall, the layout, functionality and ease of use are good.  The one thing missing that would make this a 5 star all in one service app would be the option to add in custom maintenance reminders.  Right now it basically tracks oil, spark plugs and filters.  ie. My power washer requires service to the high pressure fuel pump every X months and Y hours.  My generator recommends spark arrester cleaning and battery maintenance.  There is currently no way to add in these service reminders.  Add this option to the app and it will most definitely fulfill exactly what it set out to do.

### 3/5 — Rob

*2020-06-14*

Great to see this App. Has nearly all the features that I need.  I have one engine that displays total hours of operation. The apps recording of engine hours does not support the ability to add total hours.

### 3/5 — Great App, Could use additional flexibility

*2020-05-30, version 1.2*

I just downloaded this app, and my first impression is that it is very well laid out, and easy to use.  I really like the ability to input serial #’s and purchase dates.  As a person with a lot of equipment for a homeowner, being able to track the work I have done to maintain it all in one place is great. The basic interface makes it quick and easy to log information directly into my iPad.
      My first issue is that I have two mowers that aren’t listed; a Cub Cadet ProZ 100S EFI, and a John Deere LT150. I also have a Husqvarna 350 chainsaw that isn’t listed, and a Troy-Bilt tiller. Three of these were big-box purchases, and the fourth is a pretty common commercial mower. I mean, you’ve got Yazoos on the list....
      My second request would be for the ability to enter generic equipment with readily available small engines. For instance, I have a Cad-Digger with a Predator engine. I wouldn’t expect it to be worth the effort to add machines like this to an option list, but being able to create a custom machine description and attach the off-the-shelf engine to the equipment would be great. In addition to that, the ability to have a notes section for machine-specific parts (like the hydraulics of my digger) would allow me to log service information that relates only to this odd machine.
      Last, I would love to see the ability to add small tractors to this app. I want to log all my maintenance in one place, and that includes a sub-compact Kubota tractor (BX series). If there were a way to integrate compact and sub-compact tractors into the list, it would be amazing.  I do realize that this app is aimed at small engines, so compacts may be a stretch, but common sub-compacts like the BX and Deere 1000 series would be amazing. A lot of homeowners are buying these instead of lawn tractors these days. 
      In summary, I like the app a lot so far.  Three stars because a handful of my small equipment isn’t available on the list currently.  It would get four if it was all there, and five if it had the function to create custom equipment using common engines and maintenance features that are already in the app.
