Synthetic motor oil?

[Big country]

I'm thinking about making the switch from Castrol or Valvoline 5w-30 to a synthetic motor oil. I will not use Pennzoil and I'm not sure if the two brands I like have a synthetic. I hear Mobil has a good synthetic, but I don't know for sure. Anyway what I want to know is do I use the same wait (5w-30) in synthetic or dose that have to change. And what kind of synthetic do y'all use?

I use Pennzoil and nothing else. Last two trucks I've had both had over 200K miles on them when I traded/sold them. I did change the oil every 3-4K miles, though. Have you had a bad experience with Pennzoil?

No I have had a bad experience with it. But when I worked at on of the shops I worked at that was their house brand. It tends to gum a little more than others.

Mobil 1 or amsoil

Mobil 1 in the Porsche, Castrol Dino juice in everything else.

Mobil 1. The guy that does my work swears by it, says that if you've seenthe demo engines that they show after running some insane amount, you'd never run anything else.

Do a search on Mobil1, it'll give you thier website, and there is a guided lookup for the right oil for your vehicle.

Run Mobile 1 per the owners manual and cap in my RedLine.

Okay I don't want to sound stupid but what is a "RedLine"?

It is a Saturn that came off the lot with a factory supercharger. GM rated them at 205 HP, later found to be drastically underrated for insurance purposes....

Mobil 1 is good, I think Amsoil is better in my opinion.

Synthetic motor oil is much better than your standard dinosaur juice. If you change the filter every 3 - 4K then you can run it for up to 7500 miles before it needs changing. The oil itself will last forever, it's the additive package in the oil that is exhausted, as well as trace particulates that add up.

Make sure you only use OEM filters. They are almost always tons better than the aftermarket ones. When we compared Nissan OEM filters to several brands, we found that the Nissan filter had almost 50% more media than some brands like Fram, were of better construction, and have anti-drain back valves, which some filters don't have. Wix was pretty damn close to OEM, so I've used them as well.

Gotcha! I'm thinking Mobil 1 as a good synthetic, I'll look up that web site that Jeff B mentioned and see what it has to say.

Is OEM the brand name? I've never heard that before.

Stands for "Original Equipment Manufacturer" or something like that.

Yep, that's what he's saying.

 

[oldguy]

I've used mobile one for years in my cars without any engine problems,
mobile 1 also works on guns, drop or two on slides works wonders.

Yes. Nissan makes very good OEM filters.

Thanks. Now how much does this OEM oil filter cost? And how much does the mobile one synthetic cost. And will I get better gas mileage or will my Car run better with a synthetic? I drive an 03 Nissan Pathfinder SE, I used to work in some auto shop and was asked to recommend synthetic motor oil to folks on the grounds that it simply last longer, so I did I have never until now had something that was worth the extra money to put the pricey oil into.

OEM Nissan filters are like $5 - 6 / ea. It might be more for the larger ones. The filter is one of the most important parts to maintaining bearing life and long term compression.

The engine will run cooler, and you might see an uptick in mileage. Generally with the same viscosity you probably won't see much difference, but the synthetic oil is better at maintaining flow, especially in cooler weather.

So If I'm using 5w-30 now that is what I should put in with the synthetic?
