This Scotty shill is almost as annoying as Scotty McClickbait's videos. I wish youtube would let you block Channels.
I switch all my vehicles to synthetic oil, including my old Jeep's with those leaky 4.0's, and never got a leak that I didn't already have. It's a well discussed topic across the web.

UPDATE: You really need to see Scotty's comments about changing to synthetic and surf the internet because synthetic can cause a 15 year old engine to really start to drip. Ask Scotty... 1 billion youtube views. 50 years a mechanic.
After running conventional oil in my own 2005 4runner (4.0)(140,000 miles) I decided to try synthetic oil (blend with a quart of full synthetic). Within a few days, the 4runner which had never dripped a drop of oil onto the ground was dripping some.
I switched back to conventional (Napa 10W 40) and the drips slowed down, but didn’t stop entirely. Now after a second oil change and 10 months later ALL the drips have stopped. I’ll stick with just conventional and change the oil every 5000 miles.
NOTE: I used a piece of cardboard on the garage floor to keep track of the drips. Now, after replacing the cardboard with a new piece 5 days ago I noticed there has not been even one drop SEEN in 5 days.
I have never added any additives to this Toyota engine. I do my own oil changes.
Scotty Kilmer has 50 years of mechanic car experience, had a TV show in Houston Texas, and claims 1 billion clicks on his Youtube site.
Scotty drives three Toyota cars.
BTW.. My 4.0 Toyota 4runner made more noise with the slick synthetic.

I think you might need to grow up. After many years on this forum you will find that a very large portion of us use synthetic oil in our 4runner. Also, synthetic oil DOES NOT cause oil leaks, it finds failing or dried up gaskets and shows you where they are by leaking past them. The seals in older cars, pre 1990's used to deteriorate from synthetic in the earlier days, but seals have changed and are not affected by the synthetic oil. If you don't want to fix your failing seal/s, take Scotty's advice and use AT 205 in your engine or just keep using conventional oil.

still waiting for your explanation on how "super slick" synthetic oil will cause a head gasket issue??? come on, please back up this ridiculous statement for us...
funny how you edit your post to now say you used 1 qt of full synthetic with the semi synthetic after i told you blends are 10-20% synthetic. why didnt you state that up front?? even with that, you had at best ~30-35% synthetic. as many others have mentioned & any reputable mechanic will tell you, the oil didnt cause the leak, it found a compromised gasket or part.
& now you say you change your oil with 10/40??? where'd you come up with that weight? the owners manual clearly states to use 5/30 for all temps... even in the bahamas, mon! what you did to stop the leak was called putting a band aid on it... you used oil that is twice as thick as toyota calls for!! LOL! but then again, you just told everyone a month or 2 ago to use T-IV trans fluid in their sealed WS transmissions so im not surprised you use 10/40 oil.
& as mentioned, this is not personal, you might be a nice guy, but some of the things you post on here are downright comical if not verging on possible damage to your vehicle or others that might read your comments! if you dont know what youre talking about, please refrain from posting.

The Toyota dealer used the -IV trans fluid when they did a D/F at 105,000. You need to learn to read or go back to school to make more money.

yeah & you supported them using T-IV in a WS trans! & you think a D/F takes 5 qts! LOL! your dealer & you both dont have a clue! i posted in that thread with some FACTS & you choose to avoid them as usual. i called 2 of my local dealers & they said they absolutely do not use T-IV fluid in a WS trans & one actually laughed out loud when i told him your story!
is that all you can do is make childish comments about going back to school?? you still havent told us how "super slippery" synthetic oil will cause a head gasket issue! please back up that delusional statement... not even your buddy scotty kilmer would say that!!
& i take back saying this isnt personal, you made it personal with your lame attempts at insults that are as comical as your mechanical advice! YOU are the one that clearly needs to go back to school & learn the basics of automotive mechanics! myself & many others on here have tried to provide accurate info & you just keep spewing nonsense... but thanks for the laughs!

scotty kilmer oil leak - Bing video
My 2005 4runner leaked a drip or two on synthetic, but changing back to conventional it doesn't leak a drop.
BTW Scott Kilmer made himself a millionaire with his mechanic skills. Why listen to all the turkeys on this website?

Its leaking because you have a bad gasket somewhere.

In the video he says hes talked to engineers that say its impossible, then just goes off his own experience of synthetic causing leaks in old engines to counter the statement. This is not a strong argument for your position. Besides, Scotty does confine it to old engines, like that old Celica and even so he does note he is going against the advice of the engineers. Engineers that, you know, just design and test synthetic oils. He's sort of dropping a hint about his position.
He probably did fine as a mechanic, but applying that to youtube and being ahead of the curve there is how he made serious money. Your appeal to authority is irrelevant.
Why are you even here if you dont want to listen (read) and have a conversation?

Scotty made millions making shotty videos with clickbait titles and annoying camera work. There's teenagers making hundreds of thousands of dollars playing Call Of Duty and letting people watch, does that mean they should be training our Special Forces then?

What have done on my high mileage purchases is to add MMO to the conventional oil to clean out the carbon build up. Then switch to mobil1. If a leak at the rear main seal starts, I use AT205 which softens the seals and stops the leaks.

Don’t know if this helps, bought my 07 with 70,000 miles, switched to Mobile 1 full synthetic right after purchase, just rolled 120,000 miles and still looking good, no leaks. V6 I forgot to mention.

Which oil passage causes the HG leak? I searched the subtitles of that scotty video, not a single sentence mentioned head gasket, so I'm curious where this information is coming from.

Where did it leak from? Valve cover, timing cover, crank seal, oil pan? In all seriousness, I'd be interested to hear where it was leaking from.
The original question here was asking for feedback on switching to synthetic oil in regards to leaks, but now you're denying everyone's first hand experience and calling us turkeys. Its totally fine for us to use synthetic and not have any leaks, and its totally fine for you to use conventional.

No more synthetic oil for me.
Scotty Kilmer says the same on older cars. Synthetic oil causes oil leaks in older cars.
See Scotty right here talk about changing to synthetic. scotty kilmer oil leak - Bing video
Anyone else experience this issue?  |
I have switched more than one vehicle over from dino to synthetic. Experienced some slight leakage right after changing, but those leaks went away within about 5,000 miles.
As I understand it, dino can leave some small deposits around seals. The seal hardens slightly underneath since it is no longer exposed to seal conditioners. As this layer is washed away by the synthetic, some oil gets by the seal - until the seal conditioners are able to do their thing at which point the seals begin to do their job again.
Curious how long you had the synthetic in?

FWIW I inherited my rig back in August with 205k on the odometer, immediately switched from conventional to synthetic and 1,400 miles later it has yet to leak a drop.
OTOH I had an E36 325is earlier this year that made the switch from synthetic-blend to synthetic and it immediately started leaving a few drops on the pavement when parked overnight, although all gaskets on that car were original ('95 w/ 102k miles).
IMO I don't believe it's as black-and-white as some make it out to be, I'd bet it ultimately depends on the condition of each engine (primarily the age and quality of the gaskets).
