...after switching to synthetic oil in my Titan I just had to comment on some of the obvious changes that came as a result. Everyone has their opinions and data on how synthetics help with wear, extended drains. Others comment on MPG increases, and others say they can feel the additional power in their butt dyno. Yeah, ok, whatever. I dig synthetics because they have a number of benefits, a lot of which aren't really noticeable without oil analysis or tracking MPG over a period of time.
First, let me say this has nothing to do with a SOTP dyno (butt dyno) or some miraculous increase is gas mileage, just some characteristics that changed with the engine.
Second, let me explain how anal I am when it comes to my truck. I notice any sound that is out of place or otherwise "abnormal," my wife thinks I'm insane because a noise will drive me nuts and she would never have noticed it had I not pointed it out, so needless to say I pay attention to my truck and know how it sounds.
The first change I noticed was at start-up. I know how my truck sounds and after driving home and parking the truck in the garage for a bit I had to go pick up my daughter. I started my truck up and thought...wow...that's different. The starter noise was a little higher pitched than all the times before, the engine turned over easier and as a result the starter was able to spin it at a faster speed, thus the change in pitch.
The second change was that...well...with the windows rolled up I couldn't hear the engine running. The only sound I can hear is the exhaust and the slight whine of the trans in 1st gear, but I couldn't hear the engine. Even accelerating and driving on the freeway I couldn't hear anything but the exhaust and some noise from the intake as it gulped in air. That's not to say the engine wasn't quiet before, but I could definitely hear some noise from the engine with the windows up. Now the only hint the engine is running is the exhaust note.
I pulled into the garage with my window down and the only noise I could really hear were the little ticks from the injectors and the some other noises from the accessories and trans.
I've always been a believer in synthetics, but there have been very few occasions where I can say they made an immediate difference in the characteristics of the engine.
Needless to say, I'm extremely happy I made the switch with my Titan. The bonus is that it was offered by my awesome dealer and Nissan guarantees it for 6,000 mile intervals. I mentioned how Nissan doesn't recommend synthetics and that's when he chimed in about them using Elf synthetic oil and Nissan guarantees it for 6 months/6,000 mile intervals.
Why Elf? Pure speculation here, but Renault has had a partnership with Elf for close to 40 years. Renault also has a ~44% stake in Nissan. Should be easy to connect the dots. :cheers:
Take this post with a grain of salt if you wish, but I was shocked and impressed with the change enough to write this long-*** post about it. :upsidedow
