I have a 1995 civic lx with a d15b7. The car is approaching 70,000 miles and I wanted to switch to synthetic oil. I am currently using conventional oil but this car was running semi-synthetic when I got it (at about 60k miles) and it had no problems. The car has been properly maintained and has been in our family since it was new (though I am the third owner), it also has never gone over 3k on an oil change in the last 15 years. I know the maintinence history and I don't believe that I have and bad seals since the car doesn't burn any oil at all. That being said, do you think I would run into any problems if I switched to full synthetic?

 

No problems, but it will get extremely expensive if you maintain that 3K mile change interval.

The whole purpose of synthetic is longer change intervals as well as superior protection.

The prohibitive aspect is typically the up front cost. Which is offset on the extended change interval if the car doesn't consume or leak oil.

 

Ok. Thank you. I was actually planning to go to 7500 miles oil changes as that is what Honda recommends. I Just didnt feel comfortable doing that on conventional. I also shouldnt be too expensive as I can get synthetic for $3 a quart from Blaine's Farm and Fleet, which is a farm supply chain here in Illinois.

Hey! I also know of Blaines farm and fleet. What part of of the state are you in, fellow illinoisian?

 

Uh oh, our resident Honda destroyer is trying to hook up with a well maintained Honda.... This does not bode well.

 

FTFY

 

Indeed.

 

How am i destroying cars? Ive babied my civic from 139k to 176k miles, after buying it for 995 dollars in jan '13! Thats some good care

 

Oh come now, you should know very well, the way you went about destroying that one civic publicly on the forums attempting to "fix it", will be something you probably NEVER live down.

 

A 22 year old Civic with only 70K miles? Is it getting enough warm up /run time to prevent sludge and acids forming? I have 330K miles on my '95 DX coupe, and drove it daily with (still) regular non synth oil.

 

make sure that timing belt was done.
