Alright ... Ive been debating on switchin to synthetic oil. Ive been reading threads about how its BAD but no one is sayin what are the bad effects when switchin to it... My Boy works at a nissan dealer ...and he said he never heard of but things about that, but one thing he did say is once u change u cant go back!!! So im askin for a lil help here what should i do???

 

there is a "fluids and lubricants" forum...use it

 

never heard of synthetic oil before now... what is it... something new

 

Damn all that needed? Just send him the link.

spoon feeding complete...thanks fellows

 

yea i know !!! he always talkin $hit and gettin Smart !!!

 

I've been using synthetic since 10/04 when I was @ 39.7k, now I have 99.7k, no problems.

 

my point was... never mind.
in ALL of my cars i always used synt. oils, ran them up to 15,000 miles without change, never had an issue.

 

No idea what the previous owner of my car used but first oil change after I bought it, I went with Mobil1. Works just fine.

 

yeah man.. switching to synthetic isn't bad at all.. it's very helpful for our engines.. i can't think of any reason that you would need to switch back to regular, but here's a thread about switching back to regular once you make the switch.. i know the fluids and lubricants section doesn't get as much traffic and opinions as the 5th gen section, but maybe you can join the discussion in this one as well: http://forums.maxima.org/showthread.php?t=548637

 

in your 3.5?

 

From 89k - 240k in my 95, and from 37k - 99k in my 03. So yeah, both my 3.0 and 3.5.

 

cool... i'm gonna start using synthetic in my 3.5 next oil change... i'm at 53k

 

naw i gota 3.0... i wish i hada 3.5!!!

 

bought mine with 21k...had synthetic ever since...I have about 130k, runs great.

 

the only real downside to synthetic ive heard (and im not sure if this is accurate or not) is that it is more likely to seep/leak out of your valve cover gaskets. its not a dramatic difference, like a VCG that leaks with synthetic will also leak with dino, but its something to pay attention to.
as someone who is now having to replace his valve cover gaskets at 47k, i know

 

ive never heard of that synthetic oil leaks, i dont know why it would, worked a oil change place for a while and and all the customers love synthetic. you can go for the synthetic blend if your worried

 

if your engine is in prefect condition, synthetic is better for the engine.
if you are burning oil, it will be worse with synthetic.

 

feel like i could fly with synthetic, maybe that's just me

 

 

The only problems with synthetic are cost and the tendency to leak more when a leak is present. The cost issue is not bad if you buy Mobil1 in the 5qt jugs at Wal-mart. It's such a good deal that I choke down the vomit long enough to go in there and buy it

IME, synthetics are superior in every other way. You need not do any flushing or other garbage when changing types. Just drain old and pour in new.

Too many people make this complicated. They change around viscosities, they try to overextend their oil change interval, they spend $15 for an oil filter. My theory is use synthetic and change oil and filter every 5k.

Other than I go 6k in between changes, I agree completely. I know some people go 7.5-10k on synthetics and I am sure that is perfectly fine. To my way of thinking though, more frequent oil changes are cheap insurance.

Using dino oil in my old Chevelle, I changed it every 2500-3000 miles. From the 55,000 mile point, my car was at the dragstrip every other weekend for a year and a half before I bought another engine with a lot more cam and compression. When we tore down the engine after pulling it, with 96,000 hard miles on it, the oil pan was absolutely spotless and all the cylinders needed was a clean-up hone. Other than the lack of cross-hatch in the cylinders, the engine still looked brand new inside, ever single moving component (cam, rockers, etc) were all still within spec.
