Feedback: Proper Oil Specs and Brands. Also, synthetic vs. blend vs. dino oil

Current 02’ Tundra has had oil 5w-30 changed every 3-5k miles. Miles are sitting at 157k. Switched from dino oil to synthetic blend at about 120k.

Questions: Make the switch to full synthetic? If so, do the ‘high mileage’ synthetic? What brand do you recommend?

Thanks in advance.

 

I had a '06 and only used full synthetic since I bought used at 20,000 miles. Changed every 5,000. Gave the truck to my nephew at 280,000 and was still running like new. Mobile 1.

 

I would go regular full synthetic, first change at 5k then 8-10k afterward. Mobil 1 great choice.

Not sure what the High Mileage stuff is about. If no smoke or leaks just use regular synthetic. Under 200K not really High Mileage for Tundra.

 

Switch to full synthetic Mobil 1.

 

The Mobil 1 looks like the best. Will use the Mobil 1 with their filter on next change. Thanks for the input.

 

Do not know anything about the Mobil 1 filter. Consider the WIX (for synthetic), cannot go wrong and about the same price or lower. Many still use Toyota OEM as well.

 

One vote for an oem filter.

 

Personally, I'm a fan of Vavoline full synthetic. I have used it on all of my vehicles for the last 18-20 years or so.
The main reason I like Vavoline, is when I change my oil after 5000 miles it looks like the day I poured it in.
It smells used but it doesn't look used. If that makes sense.
