I am not familiar with the terms Universal and Standard relating to oil...They were in Larry B's post as pasted below. I just bought a 85 300D and will be changing to synthetic due to easier starts and less wear in the winter. In talking to Rusty he mentiond not to go straight to synthetic but to do a blend for the first two oil changes to get the engine used to the synthetic for numerous reasons not stated but it makes sense to me. I am also looking into the Harvard filter but will still change the filter every 3k miles regardless of the type of oil used and will probably change the synethic oil every 5k period. However....my main question is the universal and standard difference and is blend a good idea as have seen it mentioned on some thred that it is not good. I will not be using any oil that is not API CH-4 4 rated and from what I have read will go with Delo. Since this is a low mileage car I am getting(for me anyway) I want to keep it clean and long running. I presume when discussing Delo, you are referring to Chevron DeloŽ 400 Multigrade Heavy Duty Motor Oil. Thanks for your thoughts. I am a bit new here and appreciate all the experience and sharing .
