Engine is Toyota 5.7, 159000 miles. Have been using Mobil 1 0w20, OCI's range from 8-10K. I recently came across 10 gallons of free Castrol Edge 0w20 full synthetic oil. Who thinks it is safe to use the Castrol in the same manner I have used the Mobil 1 in the past? Also, no, I have never had an oil analysis done, and don't want to.
I also have a lot of Idemitsu 0w20. Would you run this over the Castrol?
Last, the Castrol edge has to be better than toyota bulk oil, right? If a Rav4 I have was doing 10k on bulk "synthetic", a junk blend in reality, I would assume I could go 10K on the Castrol, right?
Thanks
