SequoiaGeneral discussion forum for the second generation 2008 and later Toyota Sequoia.
This is a discussion thread titled "Factory motor oil ..", within the Sequoia forum, part of the SUV Forums category.
does anyone know if toyota ships our vehicles with synthetic motor oil?? i just called a local dealership to see how much an oil change cost. she said $34.99. I said, great, well i have an 08 sequoia with the 5.7, she put me on hold and said the service advisor said that the seq takes over 7 qts, and needs synthetic oil only, all for $89.99.
the bible says nothing about syn oils, and why use it if you have to dump it every 5000 miles???
well i got an email from toyota corporate, and it does come with synthetic from the factory. it would be nice if it said that in the manual, or had a sticker that says use synthetic only, oh well....
why would they sell a service and it not include the full amount of oil it took to service your engine? wanting a different oil is understandable but not giving you the proper amount of oil would be an issue to me and i would not buy that service package unless it included 8 Qts or atleast to the top dimple on the dipstick!

Your manual says the Sequoia ships with Genuine Toyota Oil which is available in both 0W-20 synthetic and 5W-20 non-synthetic. The manual says nothing about any Sequoia "needing" synthetic, so your dealer is blowing smoke.. The manual also says any ISLAC GF-4 approved oil is fine. As does your oil filler cap. And corporate Toyota (as well as Honda and all other Asian car makers) is adamantly opposed to extending oil change intervals if the owner uses synthetic
holy cow, didnt know that, plus i feel guilty dumping synthetic oil at 5000 miles. i just might go with the 5w-20 for the next oil change and beyond.....

1. Many people, driving numerous different vehicles, over many years, have driven their vehicles 500,000 or more miles using conventional motor oil.
The basic statement is true.
The information is anecdotal and useless because there is nothing with which to compare individual results.
2. 3,000 or 5,000 mile oil changes will automatically remove the advantages of synthetic oil over conventional oil.
Discarding an oil (rated for 17,000 miles under 'severe service' conditions) 12,000 miles before it should be, is something done by someone ignorant of new technology. This waste makes Al Gore and the environmentalists sad.
3. Toyota went back to chains over timing belts because customers don't want to be bothered changing belts. On the other hand people replace perfectly good serpentine belts because they don't know or believe they are fine, unless falling apart.
This might explain the Asian philosophy of shying away from extended oil changes, regardless the new technology of the oil manufacturers to allow extended oil changes. Let people stay with what they are comfortable.
4. You are 100% correct that ANY GF-4 rated oil will do.
So will a higher rated oil. And a quality synthetic with 3,000 miles on it will be analytically as good as fresh, new, just poured conventional GF-4.
5. If it doesn't matter what kind of oil is used, why does Toyota install synthetic oil at the factory? The factory in Japan and the factory here?
For that matter, why do you suppose all manufacturers install synthetic oil at the plant? After all it does cost more.........
1. I've become acquainted with about 10 Toyota owners with the 22RE engine that exceeded the 400,000 mile mark. By the 400,000 mile mark their engines were burning oil at the rate of about 2500 miles per quart and the owners who used synthetic didn't have a lower rate of consumption which indicates their engines were wearing at about the same rate as those who used synthetic.
2. I agree 3000-5000 mile oil changes "will automatically remove the advantages of synthetic oil over conventional oil" since synthetic costs 2-3X as much with miniscule benefits (e.g. 1% better fuel economy if the owner uses a 0W-20 synthetic vs a 5W-20 conventional oil). No American or Asian car makers approve of the practice of extending oil changes when using synthetic motor oil.
(I've checked the 2008 Ford, Chryslers and GM manuals as well as Nissan, Toyota, Honda and Hyundai)
3. Toyota used timing chains with it's "interference" motors in the 60's-80's. With the advent of variable valve timing in the late 1990's- early '00's, Toyota moved away from timing belts because VVT motors are interference and a broken timing belt = engine destruction.
4. After 3000 miles a synthetic has the same level of soot, acids and other contaminant buildup as a conventional oil. Collectively these contaminants begin eating away at expensive engine seals cause the concentration of emisssions the engine generates to increase, thereby shortening the life of expensive emission system components if not removed via draining the oil by at least the 5000 mile mark. Expensive "Super duper" oil filtration systems like those sold by Amsoil have not received the blessing of any automaker nor has the concept and designed been adopted by any automaker or by companies that own fleets of gasoline powered cars or trucks. Common sense therefore dictates the benefits of these "super duper" filtration systems are marginal compared to the disadvantages.
5. Thinner viscosity oils enable engines to get very slightly better fuel economy. Since 0W-20 conventional oils are not widely made or available, very recently Toyota began using 0W-20 synthetic in some of the engines it has used for EPA fuel economy testing because of the tiny fuel economy benefit. In other words, to get a car certified by the EPA with the highest possible fuel economy rating, Toyota used 0W-20 in the certification vehicles. EPA regulations state that if a carmaker certifies a car with a particular viscosity of oil (0W-20 in this case) it must also use that viscosity as the factory fill. So this explains why Toyota is now required, by government regulations, to use 0W-20 as the factory fill in some of its engines like the 5.7 liter Sequoia V8.
