Oil interval on 3.4l

Hey guys just change my oil at the dealer. They used Dino oil. On the sticker it says next oil change 7/25 or 5000 miles. Is this the recommend interval for Dino oil??? I was under the impression it was every 3k.

 

3-5k. Don't go past that.

 

I don't think there ever was a 3K oil interval. Maybe 6K normal and 3K severe duty.

My 70 Challenger owners manual calls for 4K.


Look here for your vehicle.

I run Pennzoil synthetic in my 3.4 I change it about every 5000 miles and I run Toyota oil filters. No issues so far.

 

2003 maintenance booklet:
http://www.toyota.com/t3Portal/document/omms/MSTOY03_MS0003/xhtml/MSTOY03_MS0003f.html?locale=en

7500 mi / 6 mo. light duty
5000 mi / 4 mo. severe duty:

• Driving on unpaved or dusty roads.
• Towing a trailer or using a car-top carrier.
• Repeated trips of less than five miles in temperatures below freezing.

In 2004 Toyota made it more straightforward 5000 mi / 6 mo:

So I guess they are right then. Recommending 5k even on Dino.

 

Or 7500 if not severe duty.

 

Nonononononono. No one should ever go 7500 on conventional.

 

Toyota didn't agree with you in 2003.

 

LOL

 

My $0.02... The fanciest of fancy oils doesn't hold a candle to a boring old conventional oil changed more often. Personally I go 3 to 5k with mine.

 

I change conventional oil every 3K. I remember back in the 70s when my Dad would change his every 2K......

 

What everyone else said. But why not do it yourself? Takes me 20 minutes tops.

 

It's pretty much a general consensus in the automotive world that in the late 90s, early 2000s that all automakers tried to give intervals that were way too high and had to subsequently lower them after fucking up tons of engines.

Check any auto maker's intervals in those years, you'll see them drop back down to 5k

 

I guess I'm too lazy lol. Dealer makes a good job anyways and only charges me 24.99 not bad.

 

I use dino and change every 4-5k. It doesnt even look too bad when it comes out

 

i just did mine Pennzoil platinum synthetic at 6000. it honestly looked alot dirtier that i thought it was going to. im just gonna go back to doing it around 3k to 4k. doesn't hurt to change it sooner than later.

 

I change my taco & 4runner every 3k or 3 months like clockwork with 5w30 synthetic blend. I do it myself and it only cost me $7 since i work in a auto repair facility and i get a discount on the oil & filter. My chevelles i do about every 3-4 months with convential oil because i don't put many miles on them, it would be once a year oil changes if i did it every 3k miles lol.

 

Depends on the engine. It's true for Toyota truck engines which don't stress the oil much (just 190 hp from 3.4L after all...). Turbo engines heat up the oil more, so synthetics can be better than dino even at low milage. Turbodiesel engines stress oil by both heat and contaminant blowby, and can degrade some synthetics faster than others (e.g. Mobil 1 is worse than Shell Rotella-T in diesels).

Interestingly, dino oil advanced by only one grade over the last decade. The 2003 Tacoma manual demanded API SL. Today's best dino oils are typically API SM.

 

This is what I was looking for someone with dino
