  1 Question
Q: I have a 20kw whole home generator (999cc engine) and the book says it needs 070185F oil filter. I can't seem to find this filter and confused about the oil. I live in an area where it is in the teens in the winter and over hundred in summer. Engine currently has 4.9 hours on it and I'm getting ready to replace filter and oil for first time once it reaches 8 hours. Can you help with correct parts.
by Steve Williams from Florida on December 09, 2012

A: The model you have selected includes the correct oil filter. We typically recommend synthetic oil for areas that get as cold as you are describing. This maintenance kit is your best option because it includes all of the necessary parts for your first maintenance check up.

We offer the 070185E & 070185B filters but not the filter you mentioned.

Maintenance Kit
The Maintenance Kit arrived in a timely & perfect condition. The cost was excellent. I plan on doing the maintenance myself, keeping a log book to show service if any problems should occur.

Electric Generators Direct had no problems with me placing my order by phone rather than online like another company did, whom I care not to mention.

Thank you Electric Generators Direct for your "GREAT SERVICE".

No Service Call Needed - Lol
I couldn't believe how simple it was to change the oil, filter, air cleaner, and plugs in the Jenny. This kit came COMPLETE with everything needed. It even had instructions for the less mechanically inclined.

Oh and get this - there was a towel in there too! I mean - who puts an oil rag in with their kits? lol

It took less than 20 minutes to complete everything that needed to be done for the bi-annual service. Make sure you run the generator for a good 10-15 mins beforehand to get... more
