I've heard this asked a bunch of times, and I've heard that cars with higher mileage are at risk, so i figured I'd get some opinions seeing as tomorrow is my FIRST oil change on my 'bird.
Ok, my car now has 62,000miles on it, no leaks or smoke... Does it sound like a good idea to run synthetic oil in this beast? TIA

 

I'd say you'd be ok if you don't have any leaks at all. I switched to synthetic in my fiero when it had 50,000 miles

 

i was always told that synthetic is made to keep new engines new basically. and that with higher (75,000-ish) miles its not worth the extra dollars. then again you, hypothetically, wouldnt have to change it as often. i use high mileage oil with some lucas additive. but i go all out because i was losing pressure.

 

any engine any time is a good time to run synthetic

 

Totally agree.

 

Unless it leaks like a chevy then it gets too spendy!!

The only way I'd ever use synthetic in any engine is with the stipulation it does'nt leak!! Other than that, well worth the money for the extra protection.

 

I switched mine over at 123k miles. The valve stem seals were hardened and cracked, so it used a quart every 600 miles. Changing the valve seals reduced that to about a quart every 2000 miles. But, it didn't leak.

"Synthetic" is too generic a term any more. Due to a court ruling, there are some products out there with "synthetic" on the label that are no better than the typical petroleum-based lube. With those, the only benefits are realized by those marketing them, new or old engine.

If you could be more specific about the brand/type you intend to use, a better answer can be given.

 

heinz wouldn't the fake synthetics still be better then plain dino ****?
granted might not have the refinement of a true synthetic man made base stock but using the dino **** and refining it even more then the plain jane stuff would still be better correct?

 

I currently use Castrol GTX.. i plan on switching over to Castrol Synthetic... good idea? bad?

 

when I use synthetic I always used Mobile 1 that's about as good as it gets

 

Ive been using royal purple for about a year and im pretty impressed with it, noticed a little difference in power when i switched to it, runs a little cooler too.

 

It sure ain't gonna hurt. Probably keep wear down on your parts for longer than the convential will.

 

Sometimes yes, sometimes no.

 

I use Delo 400. 140,000 miles on the wifes van and it is still shiny in the valve cover.

BTW, don't use synthetic oil thinking you can leave it in longer. It is still an internal combustion engine and the filter is only good for about 1500 to 2000 miles, after that it is being bypassed for the most part.

 

Baloney.

I've been doing 1 year/25k mile oil changes with filter changes at half that interval with AMSOIL for 22 years. I have six vehicles currently, none with fewer than 145k miles on them. I haven't worn out an engine yet.

I will agree with you, though, if you're using one of the faux synthetics. I've never heard of Delo 400, what is it?

 

but just as 57 said there is a difference between types of synthetics and for the price castrol is still a false synthetic but rather a highly refined dino juice. mobil 1, amsoil, and others are real synthetic that typicly last longer and work better
I would recomend staying with them instead

 

Delo is really made for diesel engines but I asked a guy from Jasper Engines about it and he said that since it is made to handle the torcher of a diesel it will handle anything I do with an engine.

Today was over 100 deg, 30 min drive and oil pressure was at 65psi at idle.

 

I don't see why not. ~60K on the clock, you should be fine unless there are problems somewhere, but you'll find that out quick. lol

 

I'll bite... explain please.


Delo is a big rig oil and also used alot by motorcycles that have wet clutches, though from what I've heard, not the preferred brand.
