Wazup guys, i wanted to know what type of motor oil should i use my car got already 125,000

 

125k.. Is there synthetics in there already? Do you know the condition of the motor and seals? I would recommend synthetics but sometimes it can cause more worse then good.

 

^ I agree

 

ive got 147k. since 92000, when i bought it, ive put royal purple 5w30 with K&N oil filters. nothing less. no front/rear main seal leaks, or leaks anywhere for that matter.

 

i be using synthetic oil 5w 20 but i went to the auto part today an they told me i got it start using 5w30

 

Just use whats recommended. Regular oil 5w20. I run Penzoil with K&N filter

 

meh i tried the synthetic stuff for a while, but honestly regular oil works fine, if not better.

get some regular 5w20 and call it a day.

 

thanks

 

Myth #5 - Synthetic oil causes engine leaks. Synthetic motor oils eat gasket material and cause engines to leak. Synthetic motor oils affect engine seals and result in excessive oil leakage. Synthetic oil can’t be used on high-mileage engines. Synthetic and synthetic blend motor oils cannot be used in older or high-mileage vehicles.
Fact: Synthetic oils do not cause engine oil leaks. Deteriorated and hardened seals and gasket material cause engine oil leaks. If the seals are already leaking with conventional motor oil, they will leak with synthetic oil. If the seals are in good condition, synthetic oils may be used in high-mileage engines.



Also if you really think Conventional oil is just as good or better then Synthetic then why would Bently, Ferrari, Porsche, GM, BMW, Lambo, Bugatti, Dodge, MB, and many others all pay extra to factory fill thier high performance engines with synthetic oil? I think they have done a bit more research then we have on the subject. I woulld venture to guess that they pay the extra doe because it works better and reduces engine failures while under warranty. Just my thoughts. Car companies DO NOT spend extra money on thier production line unless it has a benificial return for them. Maybe not so much for a company like Bently or Bugatti where status is everything.

I would go with any of the quality synthetics with a Puralotor Pure One, Mobil 1, or K&N filter. Skip on the cheaper filters. I like the Pure One for cost and performance. As for the oil I would just stick with the 5w30.

 

Mobil 1 5w20 fully synthetic with honda oem filter. Changed every 3k miles

 

after 80k you should switch 5w20 to 5w30 thats what i did Mobil 1 synthetic with synthetic filter only the best for my car.

 

Was doing 10-15k oil drain intervels with Amsoil 100% synthetic 5w30 along with Amsoil filter. No problems, oil analysis came back excellent.

 

5w-20 or 5w-30 is fine. Acura changed it from 5w-30 to 5w-20 for CAFE standards (slightly improved gas mileage). They are interchangable in our engines. Some like like lightness and improved MPGs of 5w-20 and others like the added protection of 5w-30.

Personally I use synthetic 5w-30 with 8k intervals. I use a good filter. I rather base my oil change interval on the filter then the brand of oil.
My last oil change I put in Mobil 1 EP for the first time since I owned the car and will be running that for a year since I drive less then 15k in a year.

I say keep using synthetic with 5w-20 until you get a leak.
If you can find it, this stuff is the best of both words if you do develop a leak or burning oil:


Notice that its not the syn blend or dino type.

I would switch long before that.

Honda uses thin oil for fuel economy. I highly suggest running 5w-30 after the break-in oil from the factory has done its job.

 

Mobil 1 is the same as any other synthetic oil most ppl think its the best but they (Mobil) pay the most for advertising . . .maybe you should look at some independent tests most ppl don't and just base it off what they think so its merely an opinion. When Royal Purple first hit the market they obviously did their homework and believed in their products and had the tv show Horsepower on Spike test the oil in a 02 Camaro SS (LS1), they swapped out all the fluids with Royal Purple dynoed before and after and gained about 8 whp

Use whatever you want but I'll stick with Royal Purple.

 

that very episode is why i switched to royal purple years ago.

 

im sold, putting 5w-30 Royal Purple oil and tranny fluid in my car this week....

 

Mobil 1 isn't a 100% synthetic anymore, they dropped off that list couple years ago when they changed the formula.....

 

I did not hear about that one. Do you have any info on that? Source? Just want to read it.

I've been using a lot of Valvoline synthetic. I usually use it or Mobil 1. Just depends on which one is on sale. One or the other seems to always be on sale with a good filter when I need to do a change. I just tried Pennzoil Platinum in my wifes car last change and when I was done there was a bunch of brown stuff in the bottom of the jug. I won't go with them again. It was likely thier additives.

 

SPoolinspOON is right. the high mileage mobil 1 is the original fully synthetic oil

 

Mobil 1 uses a group 3 base stock. Years back they used group 4. They are one of the larger companies that dropped back and not many people know about it. I found out on bobistheoilguy.com as I do a bunch of reading on there. On another note, the Purolator one filter is a pretty good filter for its price of ~$5. Build construction is pretty good as well. You can go through two of those and outlast a M1/K&N oil filter.

BTW, the M1 and K&N oil filters are very much the same filter.

 

Thanks. Guess I need to start reading again on BITOL!

 

Yeah...I think the RDX uses synthetic oil as its standard.

 

Valvoline full synthetic and a Honda filter.

 

I always thought the dealership was putting synthetic oil in my car, but Honda motor oil isn't fully synthetic =[.

I recently switched to Royal Purple as well. At 170k, I don't know if it will make any difference. No problems at least.

 

Bob is the oil....lie?

 

Read Oil 101 yesterday afternoon and switched to mobil 0W-20 Full Syn last night (was using mobil 5w-20 full syn). Thanks for that link, it was extremely informative and a good read!

 

5w 20 and I'd have to disagree that synthetic doesn't cause leaks. It penetrates better than regular oil. I just started having oil leaks after switching to synthetic. NEVER had a problem before. But synthetic does make a difference, for better and worse. Granted all cars aren't the same or in the same condition so some will never experience leaks but some will.

 

Oh, my bad. That was a type O. BITOG.
