Oil Issues

[f_399]

Scenario:

1997 3100 using Amsoil/Royal Purle Synthetic 10w30 using K&N filter since 50,000 Miles

 

Currently: 146,000 miles

 

Issue:

The car has been pretty reliable but now it has a minor oil leak(oil seems clean an no signs of coolant mixture)

 

I want to move backk to regular oil and maybe a thicker grade to compensate for the leak

 

What brand and oil grade would you recommend?

 

Also being an old car I dont know if I want to continue on investing in expensive oil

 

I will still keep using K&N filter no matter what oil I use.

I'd try this stuff and follow the directions for seal leaks. Follow the directions to the letter.

I'm currently in the first rinse phase. My rear main and front seal leaks have slowed quite a bit. I'm hoping that it will eventually stop.

you could try carquest(valvoline) 10w40. i'd just use a delco filter, but if you think you need to spend ten bucks on one, go ahead. not sure about the auto-rx seal leak stuff

wheres it leaking from? Ams is desighned to be on there for quite a while, and i actually had my filter start leaking. if its leaking, its not the oils fault. even thick oil is going to leak. Fix it, cause ams is worth having in her....

what would be the best oil for an engine with 145,00+ miles?

[boulevard]

AMSOIL 10W40 w/ AMSOIL OIL FLITERs ONLY! but thats a opinion. Good Luck! Only be bought thru special dealers. Locate one online.

I would try a cheaper semi-synthetic, or one of the high mileage oils. Personally, I just use whatever is cheap and change it and filter every 3k. Oil changes don't take long to do. My engine had about the same mileage as yours and no leaks/burning of oil. On my old 2.8 I tried Castrol Syntec once but realized it was retarded spending so much on an old engine w/ 170+miles so I changed back to GTX/whatever and had no issues.

[f_399]

yeah i need to change oil soon and dont know if i should continue with amsoil

 

i have a small oil leak...

Semi Synthetic is just a ploy to get you to spend more money on oil...no benifits.

 

My old '88 2.8 Cutlass had no problem running Pennzoil 5w30 even at 200k...it leaked maybe half a quart in 3000 miles...ran damn good too.

 

I run 5w30 Pennzoil in my current cutlass and the engine still looks like new inside

just fix the oil leak, its probly a matter of one gasket that is leaking, no sense in jimmy rigging something when you can fix it in the first place.

I agree that you should go with a heavier weight oil than you have now. Stick with the Amsoil. I definately agree that you do see better results when you use their filters too. Keep it Amsoil

[1990lumina]

You can try that stop leak, however it didn't stop shit in my dad's car from leaking...so I usually just say fix whats leaking because that other stuff is just a bandaid that sometimes doesn't work

valvolines duriblend is mixed at high heat to round all the molicules for better flow. worked for them for a while and the shit actually does outflow standard dyno oil.

[f_399]

my car is due for an oil change and i have been searching the net regarding what oil to use....

 

from what i read i should definitely stick with full synthetic

 

now... should i keep using amsoil/royal purple or go back to the "cheaper" mobil 1?

 

also was using 10w30 but the car is suppose to use 5w30.... which grade should i use?

From what I heard, Mobil 1 is about the best synthetic you can get outside of RP/Amsoil.

[gp90se]

in the warmer weather, id use 10w30, try the royal purple this time, if you dont like it, you can always go back 2 mobil 1

[f_399]

i have been switching from royal purple and amsoil.... its getting to be a little expensive

[digitaloutsider]

Unless you beat the shit out of your car on a daily basis, I think it'd be pretty safe to use Mobil 1..

[pitzel]

If you're Canadian, and have an Esso/Imperial Oil distributor nearby, Esso XD-3 Extra 0W30 is a full group IV synthetic, generally shows lower wear than Amsoil and Mobil-1, and costs about $4/L, far less than Amsoil, M1, or RP.

 

I am so glad I said goodbye to the 3k mile oil change, and I am now half-way (2-years, ~12k miles) into a 25k mile oil change and my XD-3 0W-30 is still performing well, with no loss of fuel economy whatsoever, and no visible sludge or varnishing when I put a flashlight down into the filler hole.

 

As a bonus, the 0W-30 viscosity makes cold starts very easy compared to 10W30 oils.

[f_399]

ok... switched to Valvoline Max Life 10w30 using K&N Oil Filter

[ShockTherapy]

still leaking ?

[f_399]

havent checked yet but i am pretty sure it is....

 

its better to leak valvoline then $$$$ amsoil/royal purple
