Round Three – Spotlight on Synthetics

r3syn[1]The results of the third round of synthetic motor oils examined by PQIA are in.

Each of these brands meets the requirements of an API SN, ILSAC GF-5, SAE 5W-30 engine oil. Read on to view the most recent test results on synthetics and to view the results of those previously tested. Click here for the most recent test results.

  1. Hello Tom;
    Made comments recently and wish to hear from your response to those comments.
    I am concerned that you are mixing PAO with GroupIII+ lubes,and as shown on some of the test parameters you cite ,there are dramatically differing results. One PAO Has a NOAK Viscosity % at 3.5%,,and you will compare some real differences. There ARE NO SECRETS TO THAT RESULT, JUST MORE COSTLY ADDITIVES. CHECK THAT BRAND FOR TEMPERATURE CONTROL,and you will see 475 Degree capability at 2 times extended test parameters.That is not possible with typical Petroleum lubes.
    I am your best booster,and greatly appreciate your personal commitment to quality in the Lube Industry,as are the those innovators who have developed new technologies/techniques/extended drain intervals,for the ultimate consumer,whom your effort directly represents.
    Thank you,Again, Big Al B

  2. Thank you, your comments are appreciated. Whereas PQIA’s mission is to serve the consumer of lubricants by testing and reporting on the quality and integrity of lubricants in the marketplace, it would not be appropriate for PQIA to comment on issues outside the scope of our testing (the composition of the base oils used in products we test is one example). We are, however, interested to read what others on the PQIAblog have to say about your post, and, once again, we appreciate you taking time to write.

  3. It’s great that you have tested 17 different synthetic oils. Their popularity and use are most definitely increasing. I am curious as to why Amsoil products are not included? I’m aware that you did test Amsoil’s Signature Series in May 2012. However, no mention of synthetic was made and the averages it was compared to were 12 conventional and 1 blend. Seems to me it should be in the synthetic group in order to compare apples to apples. Also, I would like to see MAG1, Amsoil XL, and Amsoil OE, all three of these are API Licensed synthetics. These two Amsoil products are showing up in a significant number of independent quick lubes as a synthetic alternative to conventional and major brand synthetics. Mag1 has several oils in the top 100 in sales on Amazon.

    Thanks for great work you are doing for the motoring public!

  4. Can you do ACEA testing on the synthetics too? A1/B1, A5/B5, etc.
