Castrol edge full synthetic

People need to get this ''only make it to the end of the warranty period'' deleted from their noggin. It's not changing your oil every 50k, or never that creates that. Toyota wouldn't be still in business recommending 10k mile oil changes if they only went 100k. We've got well over 100k miles on our 2012 prius doing only 10k mile oil changes with a number of different synthetic brands that were used by these different auto shops, and it runs great...doesn't burn a drop of oil. The last service tech says you'll get over 250k, just like others he's done with the same oil change schedules. Chances are something else major will fail before the engines ever will.

 

Not how it works man. Please do some more research before posting made up stuff bud. It confuses people looking for the correct answers.

 

I don’t care if you change your oil at 2k, 5k, or 10k. You’re likely going to rebuild your transmission twice before the engine needs to be rebuilt.

 

107k on my 2020 Limited using this oil and it's fine w/10k oil changes. I can confirm this because I had warrantied engine work done at 100k to repair a bent/damaged piston guide rod and related loss of compression to the #5 cylinder. To do this the entire engine was pulled from the truck and the warranty company wanted high resolution photos of the inside of the cylinders as well as the head/pistons to verify there was no buildup or oil-related issue they could blame to get out of paying for the $6k repair. The dealership did so and said the inside of the the engine still looked brand new, no buildup or residue, leading to the warranty company paying for the repair. Just my 2 cents' worth.

 

Just imagine how much newer it would have looked if you changed your oil twice as often

 

Many are still going to say changng your oil at 10k was the main reason. Imo, they've become brainwashed. Not all Toyotas are a sludge engine.

 

Do you know what correlations are?

 

Tolerances are a lot tighter on modern engines. This prevents the insides of the cylinders from getting properly lubricated. I mix a bit of 2-stroke oil in with every tank to make sure the insides of the cylinders stay properly lubed.

No I don't. Don't do that.

 

Use marvel mystery oil doing that. Its a trick from way back in the day.

 

People pull the "tighter tolerances" bs all the time on here and it makes me cringle lol.

 

Yes, Castrol or Amsoil is all I run in my vehicles. Mobil 1 is a marketing ploy.

 

This is beautiful

 

I’m more so saying that this is an 2 variable correlation.
Yes the ratio in engine displacement vs oil volume and being correlated with mileage of the OCI.
5.8 qts for a (2.7l total displacement) 4 cylinder engine is a LOT more oil per liter and cylinder compared to the 6.2 oil quarts for the (3.5l total displacement) 6 cylinder engine. The 4 cylinder has a higher oil volume to displacement ratio so I say that oil should last longer ran in that engine. There also is only one upper auxiliary chain I believe and a much smaller main timing chain on the 2.7 4 cylinder.
Less friction means less wear and dumping residues into the oil.
An engine that has more oil should be able to go longer and depending on if it’s problematic also, requires less checking also than one with a lower volume. If you are burning oil then the larger engine is less troublesome in the long haul since it will require less top offs (more accessible oil).
there is more volume for the heat and byproducts if combustion to go to as well which would help keep the oil cool preventing vaporization. Let me go further and say that V6 engines actually require more maintenance than a 4 cylinder engine due to making more power and having more moving parts.

 

I think you have amsoil and mobil 1 confused.

 

Agreed, I'd advise just follow what the maintenance schedule says. I freely admit that I'm not smarter than the people that built the truck.

 

Your logic is sound, although there are too many other variables in play outside of displacement, cylinder count, and oil volume. Correlations can be interesting, but they often lead us to the wrong conclusions.

 

I think you guys are confusing correlations with guesses. This is awful. I just can’t. I’m sorry. Follow your manual or this equation that a random on the internet dreamed up. The choice is yours.

 

The fact of the matter is, if it's GF-6A, it's damn good oil. Amsoil, Mobil 1, Pennzoil, Castrol.. they're all very good, especially the flagship "extended" versions. Try them out and see what your cars like. Different engines like different oils. I think that's half the reason people get so hung up on this stuff.

 

I still use Marvel Mystery Oil at every 5k change. Been using it since new and doesn’t burn a drop at 160k.

 

No Royal Purple fans?
