Conventional oil void warranty?

dubhov · 06-05-2011, 08:24 AM

So I own a NISMO, and have been using conventional for the last 5 oil changes religiously at 3k miles. I just had a service guy tell me that NISMOs REQUIRE their synthetic blend and it could void my warranty without it. I've never heard this before and think it's a load of BS. Anyone ever hear anything like this?

Not true. The 370 does not require synthetic.

if I owned a Nismo the dealer would be doing the scheduled maintenance

Why? Its no different then your normal 370 when it comes to service.

I believe that synthetic is "recommended by Nissan" not required, if this service department has any other information from Nissan requiring it then he should be able to provide it to you.

It is recommended.
There is legal precedent (in another thread) that they cannot force you to use "their" oil.

They are just misinformed (or possibly lying).

I would use synthetic rather than conventional though, especially with the heat issues in the Z.

Found the law. It's called The Magnuson-Moss Warranty Act.

Dunno about the 09's or 10's, but the 2011 manual just says the oil requirements for 370Z, Nismo included, are 5W30 oil that is API-certified and Service Classification SM. Synthetic oil not required - they don't even try to plug Nissan-brand oil (although there is an ad for Nissan oil filters in the service/maintenance manual).

This was at the dealership.

I think he just read "recommended" as "required" or "WARNING could cause problems"

Yeah, I've considered it, but I figure conventional every 3K vs synthetic every 5K, tomato-tomawto. I don't take it to the track, so I figure it'll be fine. Plan on flipping it around 30K miles anyway and let the next guy use synthetic

Any oil that has the API starburst on it and meets the current API service classification will be perfectly fine. No advantage to synthetic if you're going to adhere to Nissan's drain interval recommendations. Group III base-stock oils have such reduced need for VI improvers that VI breakdown from shear or heat just doesn't happen.
