I just inherited a stock 98 LX with 190k on the clock and plan on driving it cross country next week. Motor runs like a champ, but I don't know what type of oil it was usually replaced with. Anyway, I'd like to hear recommendations from owners with 200k.
Thanks.

 

No synthetic, if you want use some high mileage oil, or just reg oil, doesn't matter.

5w 30

 

What's wrong with synthetic?

 

I have 300K unoffically because of my speedo not working, and I use Castrol High Mileage 5w-30 during the winter months, than when it warms up 10w-30.

 

synthetic gets into all the small little places better then regular... while this sounds like a good thing... on and older motor, this will more than likly cause it to leak more oil (chances are it already leaks some)

I can vouch personally for this... i picked up some full syth a while back and ended up being a quart low after 2k miles... im normally onel 1/2 by the next oil change (needs a new oil pan gasket... among other things)

 

Any other suggestions on brands, although castrol high mileage is what I was going to go for...

 

Any name brand high mileage oil and you will be fine.

 

How much oil do you use between changes, say 1k miles a quart etc?

 

Ditto, but I use Mobil1 or Castrol Edge (depending on what's available and whichever is cheaper)

 

Absolutely nothing. It is recommend to stick with one or the other though. It's when you switch from conventional to synthetic and vice versa that the engine starts getting messed up clearances.

 

Penzoil 5w30 High mileage with an OEM (filtech) filter. If you don't get and OEM filter get a WIX, or Mobil 1 extended performance. Penzoil is excellant oil. It's ranked #2 compared to AMSOIL. Pick some up at Wallmart for $18 5 quart jug.

approx 220k here, I run castrol 5w30 year round. No high mileage bull ****.
No need for it.

Car runs perfectly, burns about half a quart (+/-) between oil changes.

 

3.5 Quarts, like the manual says. And lucky me, my D16Z6 does not burn oil. And I change mine every 3k miles.

 

Try the high mileage, you may not burn that half quart anymore. just sayin.

 

Sorry, been there done that. It's crap.

I really see no gains and/or improvements in running any sort of high mileage oil.

Regular oil is perfectly fine.

 

dude all the post ive read you that you made are wrong where are you getting your info at???? leave your opinions out of it and **** what you heard or what your homie said . stop spreading wrong or misleading info

 

I don't know where you heard that messed up clearnaces thing, but it's not true.


I have swapped back and forth, now only running conventional, and my engine is perfectly fine.

 

I recommend the Mobil One High Mileage Full Synthetic.

A+

 

i use regular castrol 5w 30 on my d15b7 with 301k on it and it runs like a champ.

 

i use 0-30 mobil.
if its leaking replace the damn seals lol.
jus tbecause its manufacturer recommended 15 years ago doesnt mean its the best to use still, there are better choices available such as 0w sseries oils.

if its leaking you are forced to use thicker oil
on cold startups it will wear your engine quicker, shortening your engine life even more.
increasing wear on battery and starter.

i would invest 30 dollars on a bottle of autoRX. in few cases it helped stop the oil leaks

read this page, lotsa good info.

just for reference. i had 2 bad bearings in my d15b.
yes i went to junk yeard and pulled 2 used bearings of same color code and put it in my engine because it wasnt worth buying new bearings for it
the crank was scuffed.

i put the recommnended 5-30 in it for a first 2 weeks only to hear a very bad knock..from both bearings. cold starts were horrible

i then replaced it with 0w-30 mobil and the knock went away only heard it knocking when it was really really cold and car sat for few days.

drove the car for 8 months or so before replacing the engine.
every day to work and to oak harbor from lynnwood etc.

raced few cars with it and finally after few months of beating on it the knock came back so i pulled the motor.

same in my wife's car the engine has a slight rod knock but its not getting worse and she doesnt go over 4000 rpm ever so its fine now.

 

Valvoline Maxlife 5W-30
With as many miles as you have, I wouldn't use Synthetic cuz it could leak/burn/plus it's kinda overkill on a (stock) D-series.
I use the Synthetic version on mine, but I have a rebuilt head and new seals, so no leaks here (except for that pesky front main/oil pump, but that's another story XD; )

But yes, I recommend Maxlife for higher mileage vehicles
Resists burning and helps recondition your seals a bit

 

so the oil pump seal leak is common on d series(d16y7 to be more specific)?
i just rebuild one and its leaking from there.
is there an article or something here about it?

 

I'd assume it's as common a leak as any other seal on a car
(meaning it's going to go sooner or later ^^; )

I honestly have no idea
As for an article on it....again no idea, I just know you have to take your timing belt and crank pulley off to unbolt the pump and replace the seal
(best to do that at your next timing belt/water pump change and get it done all at once unless the leak is REALLY bad)

As for it leaking soon after replacing...I KNOW you can't score up that pump too much or else the seal won't set in there correctly...idk without looking at it and I've never even done my own so I wouldn't know what to look for anyways XD;

Sorry dude

 

no prob just asking , i jsut too lazy to do it haha, did 3 rebuilds/swaps in last 6 months and finished building my gsr. taking a brake now lol my back and brain is hurting and so is my wallet.

 

High mileage oil is

Stick with Honda recommendation... 5w30
