You'll get many opinions for and against oil additives. I've never used that particular one but have used the Trickflow additive without issue. JMO 65

IMO if your oil needs an additive you need to buy a better oil.

words of wisdom well said.................back in the 92 i helped out a friend who had a shop ..he was a trained race engine mechanic..who was getting into daily driver repair....back then what i understood was...never use q state or penz..............to much paraffin......these oils loved to burn on top....after giving mr parr a hand for a wk to get caught up on his cust work load.........he schooled me on engineering/chemistry facts that the nascar/nhra teams/owners all knew.........there was only 1 oil co spending millions on getting it right.......valvoline.......and how many million dollar race co use valvoline ..mr parr said all of them....even those who had paid endorsements of other oil co.......of course everyone has there opinion....when the pro lube gas bag said.........oh you dont need zink addative in any oil................hummm.....passs.........

Yes, buy the oil with the correct additives already added. Adding an additive might actually reduce the oil's capability. Playing Russian Roulette [ Putin doesn't play fair....] doesn't pay.

I have used Rotelle T4 15/40 forever with Lucas zinc additive. NEVER an issue.

I don't use the stuff, but I saw the other day Advance Autoparts had Rotella 10-30 for like $2-3 a gal on clearance. You should see if the 15-40 is the same price.

I have rebuilt a lot of engines. I used good oil from the start and never had a problem. I use Valvoline VR1 in all my personal engines, except the 5.7 Hemis. There are other good oils out there, just make sure that 273 has zinc in the oil for the flat tappets.

I formulated Delo 400 for Chevron in the 1980's and '90's. I like heavy duty diesel engine oils like Delo and Shell Rotella T as they have the right level of Zinc Dithiophosphate needed for cam wear protection. I ran Delo in my '66 426 Hemi, '67 383 Formula S, '70 383 Challenger R/T and the 340 Formula S I still have, all with no issues. Heavy Duty Diesel Engine Oil has much higher levels of dispersant and detergent to keep diesel soot suspended, so it will keep your engine cleaner and especially keep the ring pack clean. The rest of wear protection is from viscosity and SAE 15W-40 is much like 10W-40, so it will work well in most older engines with no issues. The 15W just means that the oil will allow starting down to -15°C (5°F) and pump at -20°C (-4°F). Good enough for 99.9% of applications.
