Castrol Synthetic Motor Oil Choices

[Keanan]

While it doesn't directly answer you question I'll share my experience. I use Castrol Edge Extended Performance 5W-20 Full Synthetic https://www.amazon.com/dp/B00JGQM1WO/ref=cm_sw_em_r_mt_dp_U_v7Q3CbR53X0DG

I change it every 5,000 and send a sample to Blackstone labs for testing. The report always states that the oil is holding up well and could go for longer intervals.
I'm happy with the price of the oil and the performance of the oil. At $5 per quart, an oil change with a genuine filter runs me about $75.

As mentioned use a high quality full synthetic oil and change it regularly.

Read great reviews on the Castrol 03083 EDGE 5W-20 Advanced Full Synthetic Motor Oil, 5 Quart so I tried this instead. I'm sure both versions are more than sufficient given the technology and frequent oil change at 7,500 miles. https://www.amazon.com/gp/product/B00IPS3G96/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1
