Automatic E-Mail notifacation based on Date in cell

Hi All,
First off, I need to let you know that I know nothing about writing VBA code. any Help/Direction is greatly appreciated.
I know Auto E-Mail has been addressed in other posts but I am inexperienced when it comes to writing VBA code, I have looked at several posts and tried to decipher the layout of the codes, some of it I can figure out, most of it is beyond my skillset.
What I am trying to do is create a sheet with a list of machines in column A that need greased on a 90 day interval based off a date that is entered in column B. When the date in column B is reached an automatic E-Mail is sent with Outlook, this notification would repeat when the next 90 day interval elapsed.
Attached is a basic idea of what I need to do.

what I was thinking is, a starting date would be entered in say A3 and the E-mail would be sent 90 days after. When the Lubrication actually happens the date would be entered in A4 and the next 90 day period would begin.

I should also add that I am trying to understand the Conditional Format so I can apply it to the cells, I am not sure if it will interfere with the VBA Code

Sorry, To answer you last sentence, if that's what I need to do, it wouldn't be a problem opening the worksheet on a daily basis, can it be setup to check itself daily and send all the machines that are due?

I need to retain the dates of Lubrication on the Sheet for Historical Purposes, If I have a bearing go bad I need to have a reference to when and how often the lubrication occurred.
Also If I change the "90" reference in the code to say "60" the notification will happen every 60 day's correct?
Right now I have over 100 machines in different area's of the plant, different areas have different supervisors, Will I need a column to insert the individual emails into for the code to referance? I will also need to CC multiple supervisors on the Emails.

Solus, Thank you soooooooo much for helping me,

Dude...... U are awesome, Thank you

Hi Solus
Thanks for getting back to me. No its not an issue, i will have to figure out something else for that, The code with the Supervisor E-Mail is how i will need to go becouse of the different areas in the plant. if you can work the auto due date into the the code that would be Great,
Would you have any suggestions on how i could save the dates ? maybe have them move to Sheet 2? im not sure how to make this happen, i may have to just enter the dates manualy.
