Engine oil Mannol or IDEMITSU

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

Mannol Engine oil

As an additional word of advice. Do not use Mannol 5w30 C3 oil when doing oil changes. Use a high quality oil- castrol,shells, millers.. these cars are very sensitive to oil

Pros: high quality oil
Cons: Mannol oil thins out

Mannol Engine oil

VW recommends 505.01 for fixed service at 15k Km or 507.00 for flexible service at 30k Km. Since our driving condition is harsh, I usually cut those Km in half. Since you were pushing 505.01 at 12k I would recommend you use 507.00 5W30 LongLife for 15k to 18k to be on the safe zone especially if your runs are on highways. I’d highly recommend you check oil from Mannol 507.00, I’ve been using them and they are solid choice. It costs under 3.5k for 5L. You can fill 4.4L at change of oil and top up 200ml at 4,8 and 12k interval

Pros: Mannol 507.00 solid choice, use 507.00 5W30 LongLife
Cons: driving condition is harsh

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
