Is it a bad idea to do this? What are the benefits/ ill effects. I'm sure more ill effects than anything.

 

you'll proabably be fine.

 

Contrary to what some may tell you, there is no reason you can't switch between dyno/sythetic oils.

 

I don't know about switching from dino to syn, but syn to dino should be alright... unless someone tells me otherwise.

 

I've switched from synthetic to dino. No problem.

 

I remember switching from dino to syn...and from syn to dino...when I had my old 4th gen....no problems

 

Why bother?

 

Alrights cool guys thanks. BOBO f off please

 

I asked a civil question and this is the response I get! Go figure!

After almost three years of membership and in excess of 7,000 posts and you ask an inane question like this, lol!

If you can't afford synthetic oil, just say so.

 

I switched back to dino (castrol) for lower OCI's and lived to tell about it...

 

Oh I can afford it, it's just a matter of me wanting to not waste so much money on a car that has 160,000 miles. Now don't come back with well my car only has 59887.02 miles and I use . Bobo I think your only on here to cause fights and be a pain in my

 

So what is the OCI? What does it stand for and what does it mean to me? Where can I find the OCI count of a particular oil?

 

oil
change
interval

I will be switching back to dino when i do autol rx

The recommended OCI for our cars is 3,750 miles (oil and filter) on dino oil. However, if you did a lot of highway driving, you could probably extend that somewhat.

Have a nice day!

 

I have 370 miles to go on my AutoRX rinse phase and then am switching to synthetic oil for the first time (Esso XD3 Extra, 0w30, PAO, full synthetic).

 

Your engine is just getting broken in. What is your typical OCI and driving habits (city, highway, % thereof)?

 

As of now im back to mostly city driving. I change at roughly 2800 miles on synthetic.

 

isn't 2800 miles on synthetic overkill? I do realize its city driving...but can't u extend the change furthermore? I always had the assumption....5k = city miles 7.5k = highway miles......for synthetic that is

 

2800 miles on synthetic is wasting money. I used to go 7500+ miles on my Amsoil w/ a filter change inbetween.

 

i was thinking about switching back to dino. i have 100k miles and i recently got a leak from rear main seal. maybe i should start using 5w30 or 10w30 dino

 

Do two trials of AutoRX. It may fix the rear main seal leak. Ask Frank at www.auto-rx.com his opinion on the likelihood of AutoRX solving the leak problem.

 

How many months does it typically take to put on the 2800 miles?

I think you are wasting your money. Extend your OCIs like everyone says.

I plan on going to a one-year OCI when I switch to Esso XD3. However, this will likely translate into no more than 10,000 kilometres (6,200 miles) in a year, with roughly 75% highway miles.

 

how come you barely put any miles on the maxima?

 

how can it fix the leak? once mechanic told me that all Engine Cleaners destroy seals.

the car has 100k and since 50k (when i bought it) i used Mobil 1 Syn.
