SYNTHETIC OR REGULAR OIL? TELL ME

[Hershey]

PENNZOIL conventional 5w-30 be fine . The new YELLOW BOTTLE is now a SN oil . Apparently a better performer .

[1stToyota]

I'll be sending in my oil sample to the labs for a UOA, probably this week or next. Using M1 0w30 right now. Anxious to see how well their additive package held up for the 5k miles. Just guessing, but if it was conventional oil the TBN would probably show that the additive package was pushed to its limit.

[Yaris Hilton]

No, I don't think 5K miles under normal driving conditions will "push to the limit" any properly spec'd conventional oil either.

[1stToyota]

If I wasn't clear I was referring to the conventional oil being pushed by the 5k mark, and when Amsoil rates their XL series oil at only a 7,500 mile oci I'm still figuring that most conventional oils [their additive packages] will be feeling pretty tired at 5k, but not so with synthetic. Blackstone will let me know with their TBN for the M1 and recommend a better guideline for what OCI is best for it.

[Yaris Hilton]

I understood quite well, and that's what I'm arguing against. The 5K change interval is a conservative one. I'm NOT suggesting extending it. But I think it's silly to suggest that the base number analysis would suggest that the additive package of a GF-4 conventional oil would be nearly exhausted at 5K miles, but not in the synthetic. Base number analysis only indicates how much acid (mostly produced in combustion) has been neutralized by the basic additives in the oil. This kind of quasi-scientific talk really doesn't tell us that the engine is going to run better or last longer with an oil having better numbers, anyway.

I don't use any oil at all. I use water. the need for oil is a big scam by the government to
oppress and keep you down. water works better anyway and it is free.

My Yaris is almost six months old with 4,700mi. I'm using 5w-30 dealership regular oil and filter! I don't even know what brand oil and filter the dealership uses???

I live off the Allegheny Plateau in Central PA so regular 5w oil should be sufficient for the PA Winters.

If I plan to change to full synthetic it would probably be over 30,000 miles. Mainly, I'm sticking to conventional oil because of price. Also, I'm an easy driver.

I'm making double and triple payments to knock it (payments) down to under 2 years, so I don't have to pay as much interest to the criminal oligarchy of wealth and privilege... the BANKERS... I just can't afford synthetic oil right now...

Cheers!

I think TOYO oil is MOBIL Clean . Not 100 % sure .

[TheSilkySmooth]

I didnt mean to direct the syn oil comment at you personally. Just general info. Valvoline is not owned by BP but Ashland, But, Yes: Shell, QS and Pennzoil are owned by Royal Dutch Shell; My wife is Dutch - so she is OK with that ;) but she wont allow me to do her OC's with EXxon-Mobil due to the Valdez incident Me, I use the bigger WIX on my Yaris too (the one for the Camry) its about a 1/4"-1/2 longer and it works very well on the Yaris - much better than the dealer Thailand made Denso which is NOT ANYTHING like the Japon Denso filter that came on the car which was a thick foam material media not "paper". Anyone know if the Mann w610-3 cross references to our car or a subaru?

[sickpuppy1]

Now thats good to know about the wix filter! The four banger Camry I assume?
The Mann filter for the 1.5 Yaris is the ML 1009 and most all Subaru's use ML1014

[Hershey]

if you call CASTROL to get how much the ratio of synthetic to conventional oil is in their syn-blend the techs say that info is not available . What's the big secret ? Maybe that there's no synthetic in their blend . If you ask tech for S.O.P.U.S. ( PENNZOIL , SHELL , QUAKER STATE ) or CONOCO PHILLIPS ( KENDALL , 76 , PHILLIPS 66 , MOTORCRAFT (?) ) they'll give you the ratio for their syn-blends with no problem . Was told the S.U.V. Blend ( now GOLD ) from PENNZOIL is 30% synthetic and the MOTORCRAFT or KENDALL are 40% as told by their techs .

[TheSilkySmooth]

I found Korean MSDS require full component disclosure and USA do not, so if you can search a MFG website for Korean MSDS (in your native language) you should see the syn %. Most all Major US 5w-30 FULL SYNTHETIC have less than 10% syn in them !!! Figure that BS out.

Time to brush up on my korean.

Though, in Korea, they prob don't give a rats ass in what goes in their car. Their aftermarket scene isn't that great.

Damn...this oil thread has ended up just like every other oil thread. "My oil can beat up your oil". Who gives a sh!t?

The "best" oil is the one you're comfortable with. If you want to buy an $8 quart of oil, that's cool. But the person buying the Wal-Mart $1.99 special will be just fine using that as well. Any modern oil changed within a 5K interval will protect our engines just fine.

Good info ---> http://www.bobistheoilguy.com/forums/ubbthreads.php

[Yaris Hilton]

Exactly.

Thanks for that link. Great info about regular and synthetic oils, UOAs, etc...guess they're okay over there, but frowned on here at YW.

[Yaris Hilton]

Who's frowning? It's just a frivolous expenditure that's really interesting to someone with a hobby interest in oil, like the posters over there. I'm very interested in the technical details of oils and lubrication myself. I've read whole textbooks on the subject and much of what's available online, and frequently lurk at Bob's forum. I'm just being the cranky SOB pointing out that it's unnecessary. There's got to be a devil's advocate or every poor soul who asks a question on oil will come away with the silly idea that synthetics are a panacea and that their Yaris probably won't make it across town without an engine rebuild on "dino" oil. But if you need something to obsess on, there are worse things to obsess over than oil.
