RAY: You’re the rationale they jacked up the value of that lifetime oil change plan to $2,500, John.
By now, they may be placing Filippo Berio Additional Virgin Olive Oil in your crankcase, hoping to kill off your F-150 and eventually eliminate you.
Oil degrades from getting used, John. Not from sitting round. Because the oil circulates with the engine working, it gathers up contaminants and holds them in suspension.
Finally, it will get soiled, and may’t take in any extra carbon, soot or water, after which it could actually’t lubricate as properly. That’s when it must be modified.
Trendy engine oils, even a budget stuff they most likely offer you together with your free oil adjustments, can simply go 5,000 miles earlier than needing to be modified. Most likely longer. Artificial oils, that are even higher, can go twice that lengthy.
If you happen to actually uncared for your oil for tens of hundreds of miles, the lengthy chain molecules that do the lubricating would ultimately break down. However grime goes to be a difficulty properly earlier than chemical breakdown is.
So the reply is, sure, you will get much less frequent oil adjustments, John. You may strive negotiating with the seller. Say “Hey, look, you’re sick of seeing me each three months for my free oil and filter. How about you give me full artificial oil, and I’ll simply are available every year.”
They’ll pay extra for the complete artificial, however they’ll save three filters, an hour and a half a 12 months of labor and the annoyance of getting to be reminded that they’re making three bucks every time they modify your oil.
You’ll be totally protected and provides them fewer alternatives to sabotage your engine. Even when they received’t splurge for the complete artificial oil, with solely 3,000 annual miles, you’ll be able to nonetheless in the reduction of your oil adjustments to a couple of times a 12 months with no worries, John.
‘Peanut butter’ gumming up Camry could possibly be a sticky state of affairs
Expensive Automobile Discuss:
My 2015 V6 Toyota Camry has a substance that the mechanics can solely describe as “peanut butter” gumming up my heater core, coolant system and now the engine.
I’ve included an image. To date, nobody is aware of what these things is or the way it obtained there. Any thought what it may be or why it could actually’t be cleaned out after 17 occasions of draining and flushing the system? — Amy
RAY: Wow. If you happen to can work out how one can get the engine to make some grape jelly, you can begin a profitable lunch enterprise, Amy. It does look type of like peanut butter. However, sadly, it’s going to price you a lot, many jars of Skippy to repair.
I feel oil is entering into your coolant. There are separate passages inside your cylinder head for oil and coolant. And so they’re saved separate by a posh seal known as the pinnacle gasket.
If that head gasket breaks — which regularly occurs if the automotive is badly overheated — oil and coolant can then combine collectively. They’ll go both means. Coolant can get into the oil, or oil can get into the coolant, which is what’s taking place in your case.
And that’s why, regardless of flushing it out 17 occasions, it retains making peanut butter, as a result of new oil will get into your coolant each time you drive the automotive.
At minimal, you want a brand new head gasket. You’ve got two of them on this V6 engine, one for every financial institution of three cylinders. Changing each of them might be a $2,500 job.
However the information could possibly be even worse. The top itself could possibly be cracked — which can also occur throughout extreme overheating. In that case, you’d want an engine rebuild or a alternative engine. Which implies you’d be subsisting on peanut butter for some time.
There’s a slight probability that it’s transmission fluid in your coolant, coming from the transmission cooler, which sits contained in the radiator. That might be a fortunate break. So examine that. However I feel it’s extra more likely to be a head gasket or head.
I want the information was higher, Amy.
My suggestion could be to have your mechanic begin by eradicating the cylinder head closest to the entrance of the automotive. That’s the better one to work on.
If you happen to’re fortunate, he’ll see a clearly damaged head gasket between an oil passage and a coolant passage. And if you wish to get monetary savings, you’ll be able to simply ask him to switch that head gasket, shut it up and hope for the very best.
Usually, we’d substitute each gaskets, figuring if one has failed, the opposite may, too. But when funds are actually tight, you’ll be able to take your probabilities on one in every of them.
If there are not any seen head gasket breaches in both cylinder head, you then’ve obtained a call to make, Amy. You’ll be able to both spring for a used or remanufactured engine or craft a used automotive advert that features the phrases “as is.” Better of luck to you.
