I want to change my oil soon but I want to use synthetic but the last car I had it had been on regular oil its whole life and when we added synthetic the rear main seal started leaking. It might have been something else but I think thats what it was. So will using synthetic on a car that has been on regular oil its whole life create leaks? I just want to make sure so my new car will remain leak free.

mod edit: changed title from "question" to "Oil question". Having descriptive thread titles will get better answers (and thread views).

 

how many miles are on your CL? synthetic alone won't cause oil to leak

 

88k

 

^ You'll be fine

 

well Im not sure but I think the car came with synthetic from the factory.

are you looking for full-synthetic or are you gonna use a synthetic blend?

and just restating because im sure you know, that once you change to a full synthetic oil you cant use conventional oil again unless you want to mess up your engine

 

I would probably go with a full synthetic

I just dont want any leaks

 

thats what i heard before too. one of the draw backs of using synthetic: cant go back to dino.

it shouldnt leak. if you want, you can make a more gradual change over buy using a synthetic blend for a few oil changes before going fully synthetic but i dont know if that will do anything.

 

is it the same rules for the tranny I have a 6 speed and I want to go synthetic

 

advance auto is having a special right now on mobil 1. You can pick up 5qts + oil filter for 29.99 + tax. I went ahead and bought 3 sets of them.

I have a slight Rear Main Seal leak now. Kinda sucks but it doesnt really have any detrimental effects upon the car that I can see. Going to do clutch/flywheel in 10k or so, so i'm not worried.

Also when you make a new topic, please please please be a bit more descriptive with your title!!!!!!

 

The CL came with dino in the crank case.

Not true, you can go back with no problems.

 

I agree Ive already switched back and forth twice no issues
And I have 187000 KM on mine I think thats 110 miles

on Another note Is honda OEM trany fluid sythetic because I want to put synthetic in my trany but The acura dealershiip siad dont put anything but OEM honda fluid (I knew they were goin to say that they say that for every thing) Oh its an 01 CL-SA

 

I use full synthetic, 105K miles in a 12 y/o car, no leaks *knocks on wood*

 

If you want to try Mobile 1, the thread below may save you some money.

I was gona use the amsoil it said it can replace all honda manual transmission fluid heres a link

http://www.amsoil.com/storefront/mtf.aspx

this is what it says

Replaces Honda Genuine MTF fluid for manual transaxles and Texaco MTX fluid.

 

his 01 is an auto. in auto trannies, use either honda ATF or something that is honda ATF-Z1 approved.

what kind of filter do they give you?

note the starting purchase date for that rebate is april 1st.

 

How do you know if its honda ATF-Z1 approved ????

 

Theoretically it shouldn't make a difference. But it isn't unheard of for engines with questionable maintenance histories to begin having oil leaks after switching to synthetic oil at a high mileage.

Generally, if the engine has been maintained properly it should not make a difference. If the maintenance is history is questionable, then I would proceed cautiously. Also, rear main seal leaks aren't uncommon on Honda V6 engines, regardless of oil used, if the engine has been poorly maintained.

 

There's no such thing. The only ATF-Z1 that is Honda approved is the one that you purchase at the dealership. This is because Honda does not have a fluid licensing program like GM, Ford and Chrysler.

However, Lubrizol, which is one of the largest additive suppliers, has a multi-vehicle additive package that has been bench and field tested extensively in a variety of popular applications, including Honda. Therefore, you'll find many over-the-counter multi-vehicle fluids that list Honda ATF-Z1 compatibility, but not approval.

 

You probably know how the trans on the 2G CL are, would you suggest something like that

 

The failures on the Honda transmissions do not appear to be fluid-related, so I would not be too concerned about the compatibility of the multi-vehicle fluids.

 

I kinda assumed that but as far as every thing else goes I want it to last as long as possible so I was thinking Synthetic.I used it in my last two cars a 95 maxima 5speed got rid of it at 430 000km (just put a clutch in at 210 000), a jeep cherokee 5.2 litre 498 000 trans at 190 000(synthtic after that, was hoping to get half a mill)By the way the trans was perfect in both of these.

So this is why I want to go synthic with my CL-SA.

I did put synthtic engine oil in the CL ,didnt notice a difference in longevity.

I put it in my 88 300zx(160 000 Km) and it totaly destoyed my gas milage

Just thought you guys might want to know some wierd things that happened to me with synthetic engine oil.

 

Filter = Mobil 1 M-104

 

whats the best non synthetic oil to use?

 

I use castrol GTX and ever time I change my oil (5000km/300miles) it seems to still have the same consitensey

 

Is penzoil any good does it really clean out sludge?

 

I like Valvoline a lot in regular oil. Also have had good experience with their "Dura Blend" synthetic mix.

 

damn, thats a good deal then. too bad there isnt a advance auto in cali.

as long as you maintain a good interval in your oil changes, there shouldnt be too much sludge.
If your car has over 75k, i, personally, would use a high mileage oil. My mom's camry was blowing out white smoke on cold starts and after a few oil changes of valvoline maxlife, it doesnt smoke anymore. theres 220700 on the engine right now.
