Penz Plat 5w-30 in both the Camry and the Titan. 1k on the Camry, one week on the Titan. Both spiked with a small dose of LC. Lots of short trips, hope it helps stabilize the tbn.
CT here in Canada had a deal on a CT branded Full Syn oil (Formula-1) change for $27.99 - just cashed it in a couple of days ago. So, that's in my crankcase right now.
I'm debating whether to add any SLOB or VSOT to the mix.
Pennzoil Platinum 10-30 with 4oz Auto RX in the race car....Mobil1 5-40 with LC in the Mercedes....Schaefer's 10-30 with Auto RX maintenance dose in the Dodge R/T....Vette has Castrol GTX on a final rinse phase of Auto RX being sold to a guy so I'll change it tomorrow to Pennzoil Platinum w/3 oz of Auto RX and he can knock himself out....Daughter II 06 Pontiac G6 has Valvoline Synthetic 5-30 with 4oz's Auto RX.....
However, the US border is close by and there is a Biglots in Bellingham.
However, I like to do things the hard way.
So, on one of my many business trips to the US, I've picked up a few bottles of everything - SLOB, VSOT, MMO (very cheap in the US compared to CT), Seafoam,...
