2001 I30 high-mileage advice, please?

[rickfrick]

I have just made a conscience decision to keep my '01 I30 with over 151, 000 miles on it and would like some advice on what would be the best things to do to maximize trouble-free longevity. I have owned it since new (in Arizona) and have used Castrol 10w40 oil ONLY with a NAPA Gold oil filter. I stick very close to the service manual maintenance schedule.
1) I have searched the forum and the best oil seems to be a synthetic oil. Is 10w40 OK for high-mileage or should I change to a different weight?
2) From most posts, the favorite oil filters seem to be AMSoil or a stock Infiniti filter. Any preference?
3) What is the best air filter?
4) Of course, I have had the tranny serviced regulary - any advice here?
5) If ya'll have any other adivise, I am all ears.
Thanx.

If you haven't had any problems with the car, I'd stick to doing exactly what you have been doing. Because your in a relativly hot climate, I think 1040 is fine. I'd be a little reluctant to switch to synthetic @ that mileage. I've read that others have done so without problems, but if it were me, I'd leave well enough alone and just change it on sched. Routine tranny maint. and maybe power steering fluid along with brake fluid change.
Possiblly going with dino high milaeage oil would be an idea but I don't know enough about it to recommend or not. It's supposed to have seal lubricants/additives to help keep old oil seals supple.

Thanks a lot Spock for your quick, knowledgeable reply. You have confirmed what I have read elsewhere about the pitfalls of changing to synthetic oil at high mileage. I will add the other services to my master plan. What do you think of an engine flush to remove carbon - does this really work and is it worth the money?

1) you can switch but synthetic may cause some leaks since bc od the aditives in the oil, and they arent bad its just its designed to help clean up gunk. YOu may want to try a blend which is half synthetic and half regular oil.
2) i think its prefference really some use what they believe is good. i been using mobile one filter for a long time, amsoil seems to be most favorably by moist but i have never used it. i have been using bosch for a while now.
3) oem. if you just have the stock air filter a fram one or other one will do fin just make sure you check it to make sure its clean. id stay away from k&n since they use oil andmay mess with your maf and most that try to clean it will add way too much oil and mess the car even more.
4) just watch the fluid, make sure its pink or red and doesnt smell burnt.


i wouldnt do engine flush, i have heard many stories about it but i think a few will disagree but its alright. if the car is running alright dont mess with it. do the maint and it will run no need to mess with anythings thats not broken. if u use chevron or shell gass it can help to clean up or if not use some techron everynow and then and you should be fine. some of the additives people add is just wasting money. dont do engine restore or any of that engine treatment stuff. do the reg mauin and you should do fine

My personal opinion only, I've never been a fan of "flushes", but I'm no expert. What grade of fuel have you/do you run? If 89 octane or higher, I wouldn't even think about it. My advice would be that if there are no issues with the car stay away from "magic potions".

[rickfrick]

Thanks guys for the continuing advice. I have been running Shell 89 or higher octane fuel exclusively in the car since new - NEVER 87. My game plan so far is to:
1) Keep on using Castrol dino 10w40 oil as I have always used
2) Switch to Amsoil oil filter
3) NO engine flush or "magic potions"
4) Keep on running at least 89 octane fuel
5) NO K&N air filter; keep using stock Infiniti filter
6) Next tranny service; drain pan & coolant tank; make sure to drop & clean pan
7) Exchange power steering and brake fluid ASAP
8) Keep running Shell fuel as always, or alternatively, run Chevron
Movin' on - Movin' on! Any further advice on this game plan is greatly appreciated.

Sounds like a good plan to me. Have you changed the coolant? Not just the tank, but the rad also. If you feel like getting into it, you could drain the block as well.

[rickfrick]

ThankX spock for the info. I just changed the radiator, so a lot of the fluid was changed but I didn't drain the block. Looks like the procedure is something I can do myself, so I'll give it the old college try soon.

[jebhott]

why us using 10/40 in a 3.0

[spock]

If you drain the rad on a fairly regular basis, I wouldn't worry about the hassle of draining the block. It's just like the tranny fluid - if you keep up with draining a good portion of the old and adding new.... it's all good. My opinion only.
