Using Shell Rotella T4 for flat tappet engines | BobIsTheOilGuy
WEBJun 21, 2017 — Newby here and 1st post.

Rotella 15w40 T4, T5, or T6??? - Bob is the Oil Guy
WEBOct 21, 2021 — The only issues I have being an OTR driver is there seems to be a huge price difference in getting the T5 and T6 oil changes compared to T4. It seems to average about $175-$225 more for the higher grade synthetics compared to T4.

Rotella t4 in a 350 gasser. | BobIsTheOilGuy
WEBMar 19, 2022 — Junk. Worked for a construction company in central Iowa from 2006-2009 as their fleet mechanic. Most of the trucks were either late 90s Vortec 350s or 01-05 Chevy 5.3 or 6.0 LS variants. Their oil of choice was Cat 15w40, year round, as they had roughly a 15,000 gallon tank of it for the equipment.
Rotella T4 15W40 Vs Mobil Delvac 1300 Super | BobIsTheOilGuy
WEBJul 25, 2020 — This is very outdated and Im sure doesn't apply to current oils. 20 Years ago I ran Chevron Delo 400, Mobil Delvac 1300 and Shell Rotella T 15W-40 in a 1999 Cat 3406E in a dedicated route.

Rotella 15w40 T4 & T6 in Motorcycles | BobIsTheOilGuy
WEBDec 20, 2021 — I'm starting this thread to compare the two flavors of Rotella 15w40 in motorcycles. Apparently the synthetic T6 was only available in 5w40 for many years, so if you wanted a Rotella 15w40, you were looking at the T4 "Dino" oil. I've been very happy using T4 15w40 in my Nighthawk 750 (air cooled inline 4) and my Shadow 750 (liquid cooled V-Twin ...
Rotella T4 | BobIsTheOilGuy
WEBOct 26, 2019 — Shell mentions using Rotella T4 in the first post. I have been using this in an old stock 350 Chevy with a carb and a flat tappet cam. I noticed on the new bottle of T4 10W30 it does show that it meets any gas engine requirements anymore. The new bottle just shows CK-4, CJ-4, CI-4 plus, CI-4 and CH-4.

Rotella T4 in Kohler Courage 18hp Twin | BobIsTheOilGuy
WEBJun 30, 2018 — Skol8480. From what I've read on this board, it seems like I should likely consider using an oil with a higher zinc content than I have been in my Kohler 18hp Courage Twin.
