Engine oil IDEMITSU or PETRONAS

IDEMITSU Engine oil

I buy 5 OE Toyota filters at a time from Amazon ( approximately $6 ea ) Purchase Ow-20 Idemitsu oil from NAPA ( ships free to my home ) in the cost saving 6gal box ( 24 qts ) for about $125 with their online coupon. Use this in both my Avalon and my Tundra- both run like a dream.

Pros: cars run like a dream, cost-saving
Vehicle: Toyota Avalon

IDEMITSU Engine oil

This is normal. Wait till it gets below 1k rpm. Modern engines do not need a lot of time to idle after cold start, the ECU handles it. Although, for a few kilometres, do not push very hard. The engine oil (0w-20 idemitsu) is thin, and needs time to lubricate well.

Pros: thin, needs to lubricate

IDEMITSU Engine oil

Switch to Idemitsu ( Japanese oil ) - Manufacturers for genuine and even does factory fill for many, they are very premium oils with starting segment already beating the top shelf of alternative brands.

Pros: premium oils, beating alternative brands

PETRONAS Engine oil

You can go for [Petronas Syntium](https://www.proshop.ae/syntium-3000-5w-30-sn-1l-petronas.html) **3000 5W-30 SN**, a high-quality fully synthetic engine oil. It offers excellent protection, thermal stability, and performance, especially in hot climates like the UAE.

Pros: excellent protection, thermal stability

IDEMITSU Engine oil

So if you review the virgin oil analysis database, it includes idemitsu 0w-20 and 5w-30 and for both, the TBN is rather weak in comparison to other more readily available blends, also, the viscosity at 9.5 cSt for a 30w, some 20w come close to that. Does any of that matter? Not a whole lot, but it shows that there's nothing special about the oil. Generally speaking, higher TBN is better.

Pros: nothing special about oil
Cons: TBN is rather weak
