I have heard both sides on this... I am wanting to tranfer over to synthetic. I have heard nothing but good things about having synthetic oil... but I have heard some things about transferring from petroleum based to synthetic.

My '95 Maxima has 160k miles on it. Would this be dangerous? Is there anything that I should do to make the transfer happen?

Thanks!

Dangerous.....huh?
Do it, grab some Mobil 1 syn. from almost anyplace and change it over.
Some will say do an Auto-rx treatment though.

agreed ^^^^

There are no dangers in switching back and forth. But before switching I would do the following..

1) Auto-Rx and remove the varnish all over specially the varnish on the seals.
2) Run HM dino oil for 2 oil changes, it refreshes the seals.
3) Then switch to good HM syn oil.

Good luck..

Just start using it. I don't buy into the hype of these engine treatments.

The only risk is that synthetic tends to leak more easily, so you might find a new small leak or an existing leak may move a little faster. I suggest the Mobil1 High Mileage for that.

Do 2 AutoRX applications first.

See www.auto-rx.com and run a search in the Additives Forum of www.bobistheoilguy.com.

This product is only available through the website. It will rejuvenate seals, clean the ring packs, remove varnish and minimize the chances of leaking.

Those that don't buy into the hype of engine treatments, know absolutely nothing about this product. I have used it with success.

I went with what other BITOG members had to say and wasn't disappointed.

I switched mine without any tretments did not encounter any problems, wouldent recommend switching back to natural from synthetic

At 160k miles, you might have some seals that are worn out but plugged by deposits left by the oil you had been using. A good synthetic oil would unplug those seals by cleaning out the deposits. So, there is a SMALL -- I repeat, SMALL -- possibility that switching to synthetic oil will cause leaks.

AutoRX will clean those deposits and at the same time treat the seals so that they work better. It takes that small possibility of a leak and makes it even smaller (besides giving the engine a very thorough cleaning).

I'd do the AutoRX treatment if I were in your shoes.

As far as oil, Mobil 1 High Mileage 5w-30 would be a good choice. If you want to run an off-the-shelf oil, use either that or Pennzoil Platinum 5w-30.

If you wouldn't mind ordering your oil online, definitely look at Redline 5w-30 and Amsoil ASL (5w-30). Those might be more expensive, but you can run them for much longer between oil changes (10k-15k miles).

Whatever you do, make sure your oil filter is a NAPA Gold, Mobil 1, K&N, or Amsoil EaO-series.

I understand Purolator PureOne is also a decent oil filter.

Given its cost in British Columbia and lack of availability, I just stick with the OEM filter from the stealership.

Damn, forgot about that one. :

Yes, it is very good.

go get some amsoil and call it a day

Go with the high mileage synthetic.

Less chance of leaks.

PS- There is NO possible way that switching to synthetic will cause leaks. Its just that there are many more molecules in syn than regular oil. One of reasons why it flows to fast and to extreme temps. But those very small molecules make them easier to leak. That's all.

i live in CA and i use mobil 1 10w-30 full syntech matched with OEM nissan filter. been doing that for 3 years now. since the OEM filter lasts 3000 Miles, im forced to change the filter at 3k while the oil prolly has another 5k to go but i change the oil while im at it too (overkill, i know !). how long do the Mobil 1 filters last? maybe i can do 6k intervals

A33Black

The OEM Nissan filters can last longer than 3K. I use dino with OEM and change at 5K intervals.

VIP Maxima

really? if thats the case then ill do 5k intervals. i know the Mobil 1 10w30 synthec is good up to 10k

The owner's manual actually states the oil and filter are good for 7,500 miles. In practice, most .orgers change dino oil after 3,750 miles, along with the filter. I am sure the filter is good for at least 5,000 miles, if not 7,500 miles.

Dino + good filter (5K OCI -- verified with UOA). I have been running dino + OEM filter for 5K intervals since new and no oil loss and UOA's within limits.

I would think syn + good filter (7.5k -10K OCI) only after getting UOA numbers.

yea i can take my stealership filter to 5K with no problems at all on syn oil...with a good filter anywhere from 5-10K is possible
