Trying to decide whether to run a synthetic blend or full synthetic when I change my oil for the first time.


For those of you who got the "tick" after changing your oil, were you using a full synthetic when this happened or a blend. It seems like most of the cases I've read about on this "tick" is that it happened after a change to a full synthetic and this makes me a little hesitant about running a full synthetic. Thanks.

I bought 3 cases yesterday on sale at Costco.

 

I have been using full syn in all my cars for years with no issues including on my "winter" car which has 125k miles on it right now.

On my 2014 GT TP I used full syn for my first oil change. I had the dealer do it for warranty reasons, so I asked for 5W-50 Motorcraft full syn. No tick issues after the oil change.

I've always prefered full syn because on the other 2 cars I change the oil myself, and I go 7500 - 8000 miles between changes.

 

Full synthetic, either Mobil 1, royal rurple, pennsoil, AMSOIL, they all will do great job, few like AMSOIL and royal purple get alot more praise as their little higher quality full synthetics then the rest, but price and availability is a concern.

and just get full synthetic, don't be a cheapskate and put crap quality oil in your car, you can get 5 qrt. of Mobil 1 at Walmart for like 25-30 bucks most of the time.

Im about to do my own oil change in few days, and going to try out Royal Purple, will see how good it runs me.

 

Ran Amsoil ever since 300 miles. 2.5 yrs later and 4 oil changes later, runs like new, no ticks.

 

Thanks everyone.

I have a 13'Brembo car with first oil change at 6k-ish, second at 12k-ish both done by Ford dealership Full Synthetic Motorcraft 5W-20 as recommended. Tick started immediately after the second oil change.

Made another trip to the dealership this morning, I suggested to put 5W-50 hoping thicker viscosity will stop the noise, in which I was respectfully denied.

The good news is that the noise on my car is not as severe compared to those of youtube videos I researched online, that the tick seems to be fading away as more mileage is put on (but obviously it's still there).

The Research continues.

 

I run Amsoil SS 5w20.

 

Glad to hear your tick issues seems to be dissipating.

Just to clarify though, 5W-20 and 5W-50 are same viscosity. The first number indicates viscosity, the second number is the protection level, or resistance to thermal breakdown. So if you wanted a thicker oil, you could get a 15W-30 for example.

 

I heard Amsoil brand is originally came from the Tractors, is this a correct statement?

Ohhh! I thought the first number is viscosity when its cold(W=Winter), and the second number when its hot lol... between 20 & 50, there's no difference in terms of viscosity? So even if I were to change it up with 50, it will still give me the tick?!

 

No. It's from a cult that cleans carpets. In order to use it, you have to become a member of the cult and change your name to Tanya.


No, just...no. Take SAE 30 for example: the oil's viscosity is rated at 30 for the tested temperature: 210*F or 100*C. This is a standard, meaning all oils that are given the API seal have been tested using this standard. Every grade of oil is given a viscosity rating. For SAE 30, its viscosity rating is 30 at normal operating temperature (210*F).

Any numbers followed by a W are a viscosity rating tested at a lower temperature. They are also tested using a different criteria than the operating temp viscosity. They will show a rating of the oil at that tested temperature, again standardized. The lower the # before the W, the colder the oil can be and still provide adequate start-up protection.

There is a very significant difference in viscosity between 5W-20 and 5W-50. Both have the same flow rate at the lower temperature, but at operating temperature, one has a viscosity of 20 and the other has a viscosity of 50.

What that other guy told you is nonsense.

 

so I was on the right track then, at operating temp = when its hot. 50 is thicker oil, yes?

 

Yes, higher numbers are equivalent to a thicker viscosity. The viscosity is measured at the "expected" avg. operating temp for an engine, roughly 100* C. Most engines operate normally well within 10*+/- 100*C, which is why that temp is used as a standard.

 

Thank you for the kind advise.
What about synthetic blend vs full synthetic in terms of thickness? Say 5w20 sb vs 5w20 fs? Are they the same, but the other one last longer?

 

The difference between synthetic blend and full synthetic is the chemical makeup of the oil. Some full synthetics are engineered for long intervals, others for very short intervals. The synthetic quality has nothing to do with how long an oil will run. The 10W40 XPR I have in my '13 is not a long-interval oil, despite it being full synthetic made with base IV PAO's. The designed engineering of the oils determines their specific expertise.

 

No it's not. Amsoil was the first full synthetic oil sold for cars and trucks.

I use Mobil 1 fully synthetic extended performance 5w 30 and never a tick.

 

^^you also have 3.7, op has 5.0. I haven't heard of any of us 3.7 guys developing a "tick". I put in Motorcraft 5W-20 full synthetic at my first oil change, zero issues. Probably switch to Amsoil in the future.

 

I didn't have any issue on my first either. I'm starting to wonder if they used expired oil? lol

 

Oh, so its more of a 5.0 engine thing the tick is. Very interesting.
