I don't think this car has ever had synthetic in it, so I'm wondering if switching now would confer any benefit or if it would be a waste of money and possibly cause problems.

Any insight is appreciated.

('97 base model Prelude, all stock)

 

I would like to know myself. I personally think it would benefit. Better late than never?

 

Not a good idea. You're just asking for leaks. I use Castrol High-mileage 5w30. Very very good oil.

 

bad idea... dont change that far along... he's right... just asking for leaks

 

General rule of thumb on synthetic is to switch before 100k and once you do switch you shouldnt go back.

 

synthetics will clean up your gunk TOO WELL, all the gunk deposits in ur motor glues your motor together. by cleaning them off, you lose a lot of durability on basically everything which includes everything from rubber hoses to gaskets. and it may even be filling in tiny etches on your cyl walls.

 

always depends on how well you took care of your motor

Depends on hwo the motor is taken care of.

 

You should be using whatever you used to break the motor in.

Using synthetic with cleaning additives may take off the carbon deposits which could then cause leaks.

So no?

But Im breaking this rule because I went FI. I think I can deal with topping the oil level off after every fill-up vs having a blown turbo and motor.

No. Fresh engines always broken-in on non-synthetic oil. What's used after that doesn't matter.

 

at 160k i seriously forrealzies doubt that his motor's gunk-free. i mean u could run half synthetic half conventional if u'd like to try to break it in. and check on your oil OFTEN to see if you have leaks yet, i'd say at the next oil change after that you can ease into 3/4 synthetic if your results are good, and after that its probably ok to run synthetic. but plunging 100% to 100% is risking it IMO.

 

The replies that you all are giving the original poster do not coincide with what I have read in articles written by big-whigs at Quaker State/Pennzoil.

thats because they have their products on their mind. if you read big corporations explanations on stuff, it usually points in in the direction of buying their products.

it will always depend on how well the motor was taken care of

both points very true

 

If your motor hasn't displayed any signs of leaking, you should slowly convert.

Newer oils on the market that are synthetic provide the best possible protection and lubrication for high reving motors. They last longer (unless your car is leaking)and most well running, decent condition motors will benifit off synthetic oils (longevity and performance).

If it does display signs of leaking or any other oil consumption problems (other than natural break down and burning of oil) you should probably do as *vinuneuro*
stated above.

what is a good way to change over from reg oil to synthetic?

why doesnt anyone read my posts

 

yeah when you break in a motor, you should never use synthetic (veryy bad idea). You can use any oil.

At 160k I don't think it is worth it to switch over to synthetic.

What dagle said is a good idea, maybe start with a synthetic blend such as mobil 1. Or use like 1 part synthetic to 4 parts conventional, and keep raising proportions, unless you see any leaks.

 

I bought my gsr from a One owner old lady, who probably just used wal mart oil.... anyways, I bought it at 130K and Switched to Full Synthetic 10w 40 Royal Purple.. NO leaks, runs good, loves the oil...

 

Rediculous replies. Switch if you dont regularly change your oil and dont do a lot of "spirited" driving. Synthetic oil does not cause leaks. If you have "gunk" holding your engine together than repair it. If you have leaking seals or gaskets then repair them dont hide from them..

make your own thread man, don't threadjack. BTW sounds like a bad head gasket.
