10k Mile Oil Change Interval too Long for Synthetic?

3 years later

 

Point was Jiffy's lube and similar service centers marketing to convince everyone 3k mile oil changes were necessary.

Scams...that can be anyone but we can decide where we bring it to.. I'm just telling you to know when.

 

You found out why they are often referred to as 'iffy Lube

 

Mine are posted here up to the 40K change. I'll post the 50K UOA here shortly.

 

Here's my 50K UOA, along with some prior ones for reference: I now commute about 400 miles/week, so lots of highway miles. The 15K and 25K UOA's are samples drawn from the dipstick hole - not oil changes. I too was skeptical of the 10K oil change interval until I obtained these reports.

 

Doesn't surprise me at all. With my Old Accord, one time I let them talk me into a coolant flush and exchange. I watched them, they did NOT do it, then they apologized and "did it" outside the bay in the parking lot.

I can't prove it, because the Accord over was 15 years old, but it had been running perfectly. Shortly after that shoddy "Coolant Flush and Exchange" my radiator died. This resulted in a whole new radiator being needed as well as the engine which had been perfect, suddenly leaking oil because of the burnt gaskets when the engine overheated.

Never had a speck of engine problems or radiator problems until I made the mistake of letting Jiffy Lube do anything outside of an Oil Change.

Yeah, I'm never going back to a Jiffy Lube or similar outfit, I just don't think you can trust them.

 

There's YouTube now, all the "Do it yourself" automotive videos are on there. Watch it, learn it, and just do it! no more JIFFY LUBE!

 

I won a free oil change at the localJiffy Lube as a raffle prize back in the early 90's.
Not knowing any better- I brought my car in for the free service. I was shocked to see the "technician" putting the oil drain plug back in using a 1/2" air impact wrench! Not a 3/8" air ratchet... but a true 1/2" air impact wrench- the same tool they use to remove & replace tire lug nuts! And- to make matters worse- he didn't even hand start the plug- the just power threaded it in the whole way with the impact wrench.
Needless to say- I never returned to Jiffy Lube after that.

 

Someone with a bit of business savvy could likely come up with a viable alternative to Jiffy Lube and the rest of that ilk. Kind of a "Luscious Garage" for oil changes only.

 

About to turn 100 (thousand miles) have followed Toyota's recommended schedule and my oil is still almost clean at oil change time.

 

Sometimes a topic is introduced into a forum...and other points are made.

 

OK, enough with BS! Can anyone point me where it says 10K miles in owner manual?
The maintenance booklet still states 5K miles or every 6 months.

 

In Canada it's 8000 km (~5000 mi) or 6 months. But in the States Toyota's saying 10,000 miles or yearly, whichever comes first. This is from a pdf from US Warranty and Maintenance Guide:

 

Page 38 in the US 2012 Warranty and maintenance manual..

Toyota says 10k on my 2012 Prius and Mazda says 7500k on my CX5, I guess I follow what they say!
My Toyota dealer have a $99 lifetime oil change when u buy a new car w/ a 200k engine warranty.............

 

Thank you! That red thingie helped a lot!!!

 

As an aside....

After my car had 40,000 miles on it, I did an oil analysis. The results came back with good marks and the assessor at Blackstone commented that the car could probably go another couple thousand miles between oil changes should I desire to do so (I don't desire to do so).

Your Mileage May Vary. Past performance is no guarantee of future returns. Etc.

Long and short, with modest driving and synthetic oil, your car should be able to do well with 10k oil changes.
